7291095d82 Differentiate between exported and internal sdk members
Internal sdk members are used by an sdk member but not exported by the
sdk. The exported sdk members are those listed explicitly in one of the
sdk member list properties, e.g. java_header_libs.

The prebuilts of an internal sdk member use a unique name so that they
do not clash with the source module. The use of the module internally
is an implementation detail that must not have any effect outside the
snapshot. Having the same name as the source module could cause it to
override the source module, hence why it needs a unique name.

Similarly, they are marked as private so as to prevent their accidental
use from outside the snapshot.

f8539922d4 Make sdkMemberDependencyTag usable outside sdk package
Moves the struct to android/sdk.go and abstracts it behind a factory
method and interface. That allows it to be used outside the sdk
package.

This change is in preparation for adding support for module types that
have transitive sdk members.

fe1492223f Exclude sdkMemberVersionedDepTag from visibility enforcement
The implicit dependency from an unversioned sdk member to the snapshot
versions should be excluded from visibility enforcement as it provides
no benefit and would require snapshot members to be visible to their
original source modules which would complicate visibility handling.

Also, corrects a spelling mistake in sdkMemberVersionedDepTag.

e602918294 Restrict SdkMemberTypes that can be used with sdk/sdk_snapshot
By default SdkMemberTypes are only supported on module_exports module
type. Support for sdk module type has to be explicitly specified.

The java_header_libs, native_shared_libs and stubs_sources are
supported on sdk. The latter is required to provide the stubs source
for an API specified in java_header_libs as they should be kept in
sync.

255f18e584 Decouple addition of new sdk member types from sdk code
Previously, adding a new SdkMemberType would require adding a new
sdkMemberListProperty instance to the sdkMemberListProperties as well
as adding a new property into the sdkProperties struct. They are
potential sources of conflict and couple the sdk code with all the
packages that add members to it. This change switched to a
registration model that allows each package to register its sdk
member types decoupling them from the sdk code.

Adds an SdkPropertyName() method to SdkMemberType that specifies the
name of the property to use in the sdk/sdk_snapshot. Also provides
an SdkMemberTypeBase struct to be used by providers of SdkMemberType
implementations.

SdkMemberType instances are registered using the
RegisterSdkMemberType() func which sorts the registered instances
by their SdkPropertyName() to ensure the behavior is consistent and
not affected by order of registration.

When creating a new sdk module a dynamicSdkMemberTypes instance is
created that contains the following:

* A properties struct is created dynamically that contains a field for
  each registered SdkMemberType, corresponding to that type's
  SdkPropertyName().

* A list of sdkMemberListProperty instances is also created, one for
  each registered SdkMemberType.

The dynamicSdkMemberTypes instance is cached using a key that uniquely
identifies the set of registered types just in case new types are
registered after one has been created, e.g. by tests.

9ab556fd8e Added support for using static libraries in sdk snapshot
Parameterized the cc.librarySdkMemberType to allow it to support
both static and shared libraries. Created two instances, one for shared
and one for static libraries. A follow up change will add support for
libraries that can be both.

Added *librarySdkMemberType to nativeMemberInfo as information from
there is needed when generating the snapshot.

Made organizeVariants() func a method of *librarySdkMemberType so that
it can initialize the new field. Moved it to be with all the other
methods of that type.

Added host and device tests for the new module type.

a0dbf43a82 Support header and implementation jars in sdk
Add a new java_header_libs property that exports header jars (as
java_libs currently does) and switch java_libs to export implementation
jars instead.

Refactors implementation of the existing library sdk member type so
both properties can be supported from common code as they differ only
on the jar being exported.

1387957727 Parameterize the sdk member processing
Extracts the type specific functionality into the SdkMemberType
interface which has to be implemented by each module type that can
be added as a member of the sdk. It provides functionality to add
the required dependencies for the module type, check to see if a
resolved module is the correct instance and build the snapshot.

The latter was previously part of SdkAware but was moved because
it has to be able to process multiple SdkAware variants so delegating
it to a single instance did not make sense.

The custom code for handling each member type specific property,
e.g. java_libs, has been replaced with common code that processes
a list of sdkMemberListProperty struct which associates the
property (name and getter) with the SdkMemberType and a special
DependencyTag which is passed to the SdkMemberType when it has to add
dependencies.

The DependencyTag contains a reference to the appropriate
sdkMemberListProperty which allows the resolved dependencies to be
grouped by type.

Previously, the dependency collection methods would ignore a module if
it was an unsupported type because they did not have a way of
determining which property it was initially listed in. That meant it
was possible to add say a droidstubs module to the java_libs property
(and because they had the same variants) it would work as if it was
added to the stubs_sources property. Or alternatively, a module of an
unsupported type could be added to any property and it would just be
ignored.

However, the DependencyTag provides information about which property
a resolved module was referenced in and so it can detect when the
resolved module is of the wrong type and report an error. That check
identified a bug in one of the tests where the sdk referenced a
java_import module (which is not allowed in an sdk) instead of a
java_library module (which is allowed). That test was fixed as part
of this.

A list of sdkMemberListProperty structs defines the member properties
supported by the sdk and are processed in order to ensure consistent
behaviour.

The resolved dependencies are grouped by type and each group is then
processed in defined order. Within each type dependencies are grouped
by name and encapsulated behind an SdkMember interface which includes
the name and the list of variants.

The Droidstubs and java.Library types can only support one variant and
will fail if given more.

The processing for the native_shared_libs property has been moved into
the cc/library.go file so the sdk package code should now have no type
specific information in it apart from what is if the list of
sdkMemberListProperty structs.

375058f67d Use static build rules in snapshot generation
It is easier to extract information out of static build rules than it
is out of custom build rules built using the builder as the former
provides access to the in/out and args separate from the rule whereas
the latter only provides access to in/out.

Also, cleans up some warnings that appear in Intellij.

There is a lot of duplication in the testing code. That will be
resolved in a follow up change.

9154718303 Adds droidstubs support to sdk module
Adds stubs_sources property to sdk and unzips the droidstubs srcjar
into the snapshot directory.

Adds an UnzipToSnapshot method to the SnapshotBuilder which creates
a rule that uses zip2zip to repackage the supplied zip content into a
temporary zip file that matches what the required snapshot structure.
e.g. if the supplied zip contains foo/Foo.java and that needs to be in
the snapshot directory java/foo/stubs then it will create a zip that
contains java/foo/stubs/foo/Foo.java.

The temporary zip that is the output of that rule is added to the
zipsToMerge field for merging later.

If the zipsToMerge is empty then the snapshot zip is created as
before. Otherwise, a temporary zip file is created. That is then
merged with the other zip files in zipsToMerge to create the final
snapshot zip.

Adds prebuilt_stubs_sources for use by the generated .bp module.

232e785b98 SDK snapshot is dist'ed
`m module_sdk dist` produces snapshots of all SDKs in the source tree.
A snapshot is a zip file consists of Android.bp, exported headers,
exported AIDL files, stubs for native libs and jars. The zip file is
expected to be downloaded from the build server and extracted to a
directory (which probably will be
/prebuilts/module_sdks/<module_name>/current).

9b409bcd10 Create scripts to update and freeze a module SDK
`m <sdk_name>` generates two scripts each of which is use to update the
current snapshot of the SDK and to freeze ToT as a new version,
respectively. Executing the scripts will copy necessary files (stub
libraries, AIDL files, etc.) along with Android.bp into the ./<apiver>
directory under the directory where the sdk is defined.

This change also introduces a new module type 'sdk_snapshot' that
represents a snapshot of an SDK. It will be auto-generated by the above
scripts, so developers are not expected to write this manually.

The module type 'sdk' is now used to simply specify the list of modules
that an SDK has.

Finally, this change changes the version separator from '#' to '@'
because '#' confuses Make.

d1063c1586 Introduce module type 'sdk'
This change introduces a new module type named 'sdk'. It is a logical
group of prebuilt modules that together provide a context (e.g. APIs)
in which Mainline modules (such as APEXes) are built.

A prebuilt module (e.g. java_import) can join an sdk by adding it to the
sdk module as shown below:

sdk {
    name: "mysdk#20",
    java_libs: ["myjavalib_mysdk_20"],
}

java_import {
    name: "myjavalib_mysdk_20",
    srcs: ["myjavalib-v20.jar"],
    sdk_member_name: "myjavalib",
}

sdk {
    name: "mysdk#21",
    java_libs: ["myjavalib_mysdk_21"],
}

java_import {
    name: "myjavalib_mysdk_21",
    srcs: ["myjavalib-v21.jar"],
    sdk_member_name: "myjavalib",
}

java_library {
    name: "myjavalib",
    srcs: ["**/*/*.java"],
}

An APEX can specify the SDK(s) that it wants to build with via the new
'uses_sdks' property.

apex {
    name: "myapex",
    java_libs: ["libX", "libY"],
    uses_sdks: ["mysdk#20"],
}

With this, libX, libY, and their transitive dependencies are all built
with the version 20 of myjavalib (the first java_import module) instead
of the other one (which is for version 21) and java_library having the
same name (which is for ToT).
