d19f894512 Add support to sdk/module_exports to specify required traits
Currently, every sdk member of a specific module type has to be treated
in the same way as every other sdk member of that type. e.g. it is not
possible for an sdk member to use different variants to other members
of the same type.

Adding a new member type for each different way to treat the members is
not scalable as if there were N different ways treat a member then it
would require 2^N types for all the possible combinations.

This adds a new traits mechanism that allows the behavior of member
types to be customized per sdk member. Each member type can specify a
list of supported traits and customize its behavior based on which
traits are required for each member. A trait can be supported by
multiple different member types.

62782de15c Make sdk member type related types and vars type specific
Previously, some of the sdk member type related types and variables
included the words "member type" whereas others only used the word
"member" and did not include "type". This changes makes them all
include the word "type" to differentiate them from other types related
to sdk members.

5c21145915 Revert "Export implementation class jars for java_boot_libs"
This reverts commit 22ff0aaf51.

The workaround to support hidden API generation with prebuilts by
passing the full implementation jars through to the SDK snapshot is no
longer needed as the monolithic hidden API flag generation uses the
prebuilt flag files that are already part of the snapshot.

This change reverts that previous workaround.

5cca7c44e5 Support hidden API processing for modules that use platform APIs
Previously, hidden API processing could only be done by those
bootclasspath_fragment modules that either did not depend on any other
fragments (e.g. art-bootclasspath-fragment) or only depended on APIs
provided by other fragments (e.g. i18n-bootclasspath-fragment). That
meant that modules like com.android.os.statsd-bootclasspath-fragment
that depended on APIs provided by parts of the platform which are not
yet part of another bootclasspath_fragment could not perform hidden
API processing.

This change adds support for a bootclasspath_fragment to specify the
additional stubs needed to perform hidden API processing. It adds a new
additional_stubs property that can be used to specify the additional
stub libraries.

Most bootclasspath_fragments that need to use the property will need
access to the APIs provided by the android-non-updatable.* libraries.
Rather than have each fragment explicitly specify the correct module
for each scope it treats "android-non-updatable" as if it was a
java_sdk_library that can provide different jars for each scope.
Soong will handle mapping that to the correct android-non-updatable.*
module.

b97b1579d3 Remove duplicate component from sdk snapshot
Previously, an sdk snapshot could contain the following:
* A java_sdk_library_import module, e.g. "foo" which creates component
  modules "foo.stubs", etc.
* A corresponding versioned module, e.g. "sdk_foo@current" which
  created component modules "sdk_foo@current.stubs", etc.
* An internal (to the sdk snapshot) java_import for one of "foo"'s
  components, e.g. "sdk_foo.stubs"
* A corresponding versioned module, e.g. "sdk_foo.stubs@current".

That causes a few problems:
1. The "foo.stubs" is duplicated.
2. The names of the components created by the versioned
   java_sdk_library_import are invalid, as they append the component's
   suffix to the version and not the name before the version.

The latter causes problems when building against prebuilts and fixing
that causes the generated snapshot to be invalid because it contains
duplicate definitions of the "sdk_foo.stubs@current" module. One
explicitly in the Android.bp file and one created by the
"sdk_foo@current" module.

Removing the duplicates from the snapshot causes errors as the name
generated by the snapshot for the component module, i.e.
"sdk_foo.stubs@current" does not match the name generated by the
"sdk_foo@current", i.e. "sdk_foo@current.stubs".

This change fixes them together.

2d3da31d41 Make all SdkMemberTypes support transitive member deps
Previously, only those SdkMemberTypes which had specific need to
automatically add some of their dependencies as sdk members would cause
the sdk to visit their transitive dependencies. However, as any module
can have dependencies on license modules and license modules need to be
included in the sdk then it needs to visit transitive dependencies of
all members.

So, this change removes the support for allowing an SdkMemberType to
control whether its transitive dependencies are visited and just visits
them all.

This does not have any effect on sdk snapshots as in order for a
dependency to be added to an sdk it needs to be added with a tag that
implements SdkMemberTypeDependencyTag and the only tags that implement
this are used by SdkMemberTypes that had enabled transitive members.

b9e7a3ca7a Make licenseModule SdkAware
Making licenseModule SdkAware caused two breakages in the build. The
breakages were both caused by having an SdkAware module that was
depended upon by a versioned sdk snapshot but which was not itself
versioned and so did not have the member_name property set.

That occured because some default licenses have been added to the
packages containing prebuilts, e.g. prebuilts_runtime_license in
prebuilts/runtime/Android.bp. They apply to both the versioned and
unversioned members.

Once license support has been added to the sdk most of those will be
removed and replaced with properly versioned license modules. However,
in the meantime it is necessary to support that.

This change avoids the issue by checking to see whether the module is
itself versioned before relying on the member_name property. It also
improves the error message when a panic is recovered to make it easier
to identify where it originates.

22ff0aaf51 Export implementation class jars for java_boot_libs
Hiddenapi processing currently requires access to the class
implementation jars for libraries on the bootclasspath which means that
they need to be provided as part of the prebuilts. This change modifies
the java_boot_libs property on the sdk to make those files available.

Modularization of the hiddenapi processing will hopefully remove the
need for these to be exported so this should be temporary.

db170e4a92 Add java_boot_libs to sdk
The build has some implicit dependencies (via the boot jars
configuration) on a number of modules, e.g. core-oj, apache-xml, that
are part of the java boot class path and which are provided by mainline
modules (e.g. art, conscrypt, runtime-i18n) but which are not otherwise
used outside those mainline modules.

As they are not needed outside the mainline modules adding them to
the sdk/module-exports as either java_libs, or java_header_libs would
end up exporting more information than was strictly necessary. This
change adds the java_boot_libs property to allow those modules to be
exported as part of the sdk/module_exports without exposing any
unnecessary information.

Some points to note:
* The java_import has to have a valid file for the src property
  otherwise it will be disabled.
* The src property is supposed to reference a jar file but the
  java_boot_libs property will make it reference an empty file (not
  an empty jar) so that any attempt to use that file as a jar, e.g.
  compiling against it, will cause a build failure.
* The name of the file passed to the src property should make it
  clear that the file is not intended to be used.
* The test makes sure that only the jar file is copied to the
  snapshot.

caa47d7eed Disable all host OS variants except those explicitly included.
Necessary to avoid problems with implicitly enabled host OS'es, e.g.
linux_glibc getting enabled when we only supply a linux_bionic linker
in runtime-module-host-exports. That will then cause a non-functional
prebuilt to take precedence over source if the prebuilt is preferred.

We don't do this for device since we so far only support a single
device OS (android).

This introduces the notion that SDK member types can be host OS
dependent or not. That way java members with host prebuilts don't get
restricted to a specific host OS.

50f0da4205 Improve IDE navigation to SdkBase methods
Previously, it was not possible to navigate directly from the interface
methods in SdkAware to the implementations in SdkBase as the former
embeds android.Module but the latter did not implement those methods
and so did not implement SdkAware. Finding the implementation of those
methods required explicitly searching for them.

This change extracts sdkAwareWithoutModule interface to allow use of
the IDE capability to navigate directly to implementations of an
interface method.

89238f4703 Add compile_multilib properties to all native prebuilts (reland).
There was a special case in cc_prebuilt_binary only, which resulted in
prebuilt libraries getting both 32 and 64 bit variants even when their
sources only had one of them, and the other variant would be defunct
since it wouldn't get any prebuilt artefact.

This moves the handling of compile_multilib completely to the common
update code, so that SDK members don't need to deal with it. It doesn't
take SDK member defaults into account, which means a bit more
boilerplate in the snapshots, but it's simpler and less error prone
(different SDK member types have different defaults).

923e8a5e9e Extract DepIsInSameApex and RequiredSdks interfaces
The DepIsInSameApex() and RequiredSdks() methods were defined in a few
places to avoid having to depend on the whole ApexModule/SdkAware
interfaces directly. However, that has a couple of issues:
1) It duplicates functionality making it difficult to change, changes
   to the definitions outside the main interfaces do not cause compile
   time failures, instead they result in a runtime change in behavior
   which can be difficult to debug.
2) IDE navigation (specifically in Intellij) does not detect that the
   duplicate definitions can resolve to the definitions in the main
   interface.

This change extracts the methods into their own interfaces and reuses
those interfaces instead of duplicating the methods to fix both of
these issues.

a551a1c2f9 Improve consistency of handling java snapshot properties
Previously, java snapshot properties (java_library and java_test)
relied on the properties not being optimized when there was a single os
type and instead being added directly to the common os type properties.
However, that means that the behavior is inconsistent for other member
types depending on whether there was one os type or not.

This change updates the java sdk member handling to support
optimization. This involved:
1) Adding AidlIncludeDirs field to librarySdkMemberProperties to
   specify the aidl include dirs instead of extracting that from the
   library field.

2) Renaming jarToExport to JarToExport (in both
   library/testSdkMemberProperties)to allow it to be optimized.

3) Adding MemberType() and Name() methods to SdkMemberPropertiesContext
   to avoid having to store the former in the properties struct and
   retrieve the latter from the library/test fields.

4) Removing the now unused library/test fields from the properties
   structures.

5) Separating the processing of the jar/test config in
   AddToPropertySet(...) as they may be optimized separately.

6) Ditto for the jar/aidl include dirs.

7) While doing this work I noticed that although the contents of the
   aidl include dirs are copied into the snapshot the java_import does
   not make use of them. Raised bug 151933053 and added TODO to track
   that work.

3a4eb50829 Make new module creation API more flexible
Previously passing additional information to the implementations of
AddPrebuiltModule() or the SdkMemberProperties interface would have
required making changes to the API. This change added an
SdkMemberContext object into which additional information can easily
be added without requiring changes to existing implementations.

The BuildSnapshot() method was not modified because it is deprecated
and will be removed in a follow up change.

It also switches the API from passing variants as android.SdkAware to
android.Module. That is for a couple of reasons:
1) SdkAware is designed for managing the relationship between the
   module and the SDK, not for generating the output snapshot. As such
   there is nothing in SdkAware that is needed for generating the
   output snapshot.
2) Accepting android.Module instead makes it easier to use the
   underlying code for generating the snapshot module as well as the
   individual member modules.

This is in preparation for a number of improvements and bug fixes in
both the snapshot creation code and implementations to address found
while trying to built the platform against ART prebuilts.

  Then "m com.android.art.debug". This passes Soong but fails in the
  build step because more members are required.

0174d8d2c9 Remove SdkMemberType.FinalizeModule
This was only being used to set the "stl" property for cc library sdk
member type and so that functionality was moved to AddPrebuiltModule()
and FinalizeModule was removed.

Required a few test changes to move the property to the correct
position in the generated module.

13f0271478 Copy shared_libs and system_shared_libs to module snapshot
This change ensures that the runtime dependencies between a
binary/shared library are correctly specified in the snapshot so that
the build can ensure that shared libraries are built before the targets
that use them.

It adds support for differentiating between references that are
required to refer to another sdk member (required) and those that may
refer to either an sdk member or a non-sdk member (optional). The
latter is used for shared library references as the libraries used by
an sdk member may be provided from outside the sdk. e.g. liblog is not
part of the ART module but is used by some members of the ART sdk.

b07fa51196 Support extracting common values from embedded structures
This change also added support for excluding properties from common
value extraction by using a struct tag of `sdk:"keep"` That was needed
to prevent the fields in SdkMemberPropertiesBase from having their
values cleared.

The purpose of this change is to make it easier to share functionality
across sdk member types.

a04c107bfa Add support for multiple os types
Updates the member snapshot creation code to support multiple os types.
It basically sorts the variants by os type, then applies the code to
optimize the arch properties and then it optimizes the properties that
are common across architectures and extracts any properties that are
common across os types.

The java and cc member types needed to be modified to make the location
of the generated files within the snapshot os type dependent when there
is more than one os type. That was done by adding an OsPrefix() method
to the SdkMemberPropertiesBase which returns the os prefix to use when
there is > 1 os type and otherwise returns an empty string.

Added three tests, one for cc shared libraries, one for cc binary and
one for java header libraries.

88f2fbe92e Refactor snapshot module creation
Generalize the processing of arch specific properties to reduce
duplication in snapshot module creation and simplify addition of
support for handling multiple os types.

Supporting multiple os types with the current method for building
snapshot modules would require every affected module type to add
support for it. Rather than duplicate multiple os type handling code
across those module types this work generalizes the process cc modules
use for handling arch types as it can be used as a basis for handling
multiple os types. Migrating module types over to this new process
will insulate them from having to handle multiple os types.
OB
SdkMemberType changes:
* BuildSnapshot is deprecated in favour of the new AddPrebuiltModule()
  method.
* Additional methods, CreateVariantPropertiesStruct() and
  FinalizeModule() are added.
* A new interface SdkMemberProperties, is defined that handles
  extracting information from the variant (prior to common value
  optimization) and adding properties to a property set.

The sdk module type uses these new methods and types to delegate the
member type specific processing to the relevant member types while
handling the behavior that is common across all members types, e.g.
extracting common values across multiple architectures. A future change
will leverage this processing to add support for multiple os types.

This change also refactors the cc module processing to use the new
process.

7b81f5e9d7 Add java_system_modules to sdk/module_exports
Adds an SdkMemberType implementation for java_system_modules. It
specifies that java_system_modules can be used with sdk as well as
module_exports, and also that the libs property should be included
as transitive members in the sdk.

It also adds support for treating appropriate tagged properties in
the snapshot prebuilts module as references to sdk members so that
they are correctly transformed when creating the versioned modules.

Needed for the java_system_modules type whose libs property are an
