98d63e1cc7 Remove ApexBundleDepsInfo.MinSdkVersion()
For java.AndroidApp app, app.MinSdkVersion() was selected from
ApexBundleDepsInfo, not from java.Module.
This caused app.MinSdkVersion() to return "" always.

Besides, having two embeded fields and relying on depth to choose one of
them makes it hard to read.

62304bbeec Add test_for property
This change adds 'test_for' property to cc_test_* types. The property is
used to mark a module as a test for one or more APEXes, in which case
the module has accecss to the private part of the listed APEXes. For
example, the module is linked with the actrual shared library in the
APEX instead of the stub of the shared library.

89e850ab84 mark platform un-availability
A module is marked unavailable for platform when 1) it does not have
"//apex_available:platform" in its apex_available property, or 2)
it depends on another module that is unavailable for platform.

In that case, LOCAL_NOT_AVAILABLE_FOR_PLATFORM is set to true for the
module in the Make world. Later, that flag is used to ensure that there
is no module with the flag is installed to the device.

The reason why this isn't entirely done in Soong is because Soong
doesn't know if a module will be installed to the device or not. To
explain this, let's have an example.

cc_test { name: "mytest", static_libs: ["libfoo"]}
cc_library_static { name: "libfoo", static_libs: ["libbar"]}
cc_library { name: "libbar", apex_available: ["com.android.xxx"]}

Here, libbar is not available for platform, but is used by libfoo which
is available for platform (apex_available defaults to
"//apex_available:platform"). libfoo is again depended on by mytest
which again is available for platform. The use of libbar should be
allowed in the context of test; we don't want to make libbar available
to platform just for the dependency from test because it will allow
non-test uses of the library as well.

Soong by itself can't tell whether libfoo and libbar are used only in the
context of a test. There could be another module depending them, e.g.,

cc_library_shared { name: "mylib", static_libs: ["libfoo"] }

can exist and it might be installed to the device, in which case
we really should trigger an error.

Since Make has the knowledge of what's installed and what's not,
the check should be done there.

dddd5469ad Ignore PrebuiltDepTag when processing APEX contents
When a source and a prebuilt module are present in the same build a
dependency is added from the source module to the prebuilt module.
Previously, the code for generating the APEX did not recognize that
tag and in some cases (e.g. for cc_(prebuilt_)library_shared) will
fail the build.

This change:
1) Adds a test to reproduce the problem.
2) Improves the debug message by pretty printing the tag.
3) Adds a new ExcludeFromApexContents interface that can be implemented
   by a tag to declare that it should be excluded from the APEX
   contents.
4) Ignores tags that implement that interface when generating APEX
   contents.
5) Implements that interface on prebuiltDependencyTag to fix the
   test.

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.

7556839772 Enforce apex.min_sdk_version for bundled builds
Previously, when Q-targeting apexes are bundled-built, they are built
against the latest stubs.

It was because unwinder is linked dynamically in R and APIs are provided
by libc while Q apexes should run on Q where libc doesn't provide those
APIs. To make Q apexes run on Q device, libc++ should be linked with
static unwinder. But, because libc++ with static unwinder may cause problem
on HWASAN build, Q apexes were built against the latest stubs for bundled
build.

However, Q apexes should be built against Q stubs.

Now, only for HWASAN builds, Q apexes are built against the latest stubs
(and native modules are not linked with static unwinder).

f760cae41b apexDepsMutator is a top-down mutator
apex { name: ["myapex"], native_shared_libs: ["libX", "libY"] }
cc_library { name: "libX", shared_libs: ["libY"] }
cc_library { name: "libY", shared_libs: ["libZ"], stubs: {...} }

apexDepsMutator was a bottom up mutator and it uses WalkDeps to traverse
the dependency tree rooted at myapex in a depth-first order. While
traversing the tree, if calls BuildForApex for a module that will be
part of the APEX.

libY is visited twice. Once via libX and once via myapex. If the visit
from libX was before the visit from myapex (since this is a depth-first
traversing), BuildForApex is not called for libY and its dependency
libZ, because libY provides a stub. And then when libY is again visited
via myapex, BuildForApex is correctly called for the module, but not for
its dependencies libZ because the paths from libY to libZ was already
visited.

As a result, the apex variant of libY has a dependency to the non-apex
variant of libZ.

Fixing the problem by changing the mutator a top-down one.

0f80c1848a apex_available tracks static dependencies
This change fixes a bug that apex_available is not enforced for static
dependencies. For example, a module with 'apex_available:
["//apex_available:platform"]' was able to be statically linked to any
APEX. This was happening because the check was done on the modules that
are actually installed to an APEX. Static dependencies of the modules
were not counted as they are not installed to the APEX as files.

Fixing this bug by doing the check by traversing the tree in the method
checkApexAvailability.

This change includes a few number of related changes:

1) DepIsInSameApex implementation for cc.Module was changed as well.
Previuosly, it returned false only when the dependency is actually a
stub variant of a lib. Now, it returns false when the dependency has one
or more stub variants. To understand why, we need to recall that when
there is a dependency to a lib having stubs, we actually create two
dependencies: to the non-stub variant and to the stub variant during the
DepsMutator phase. And later in the build action generation phase, we
choose one of them depending on the context. Also recall that an APEX
variant is created only when DepIsInSameApex returns true. Given these,
with the previous implementatin of DepIsInSameApex, we did create apex
variants of the non-stub variant of the dependency, while not creating
the apex variant for the stub variant. This is not right; we needlessly
created the apex variant. The extra apex variant has caused no harm so
far, but since the apex_available check became more correct, it actually
breaks the build. To fix the issue, we stop creating the APEX variant
both for non-stub and stub variants.

2) platform variant is created regardless of the apex_available value.
This is required for the case when a library X that provides stub is in
an APEX A and is configured to be available only for A. In that case,
libs in other APEX can't use the stub library since the stub library is
mutated only for apex A. By creating the platform variant for the stub
library, it can be used from outside as the default dependency variation
is set to the platform variant when creating the APEX variations.

3) The ApexAvailableWhitelist is added with the dependencies that were
revealed with this change.

505221f6e0 ignore apex_available for host variants
The main purpose of apex_available is to prevent a module from being
installed to the system partition (or being statically linked to
something that is installed to the system partition). It's not the goal
to prevent host tools from using the modules.

However, since both host and device variants are not mutated for
platform when the module is not available to platform, the host tools
that depends on those modules couldn't be built. To solve the problem,
the platform variation is NOT skipped for the host variants.

127b40b316 Add apex_available to control the availablity of a module to APEXes
apex_available property controls the availability of a module to APEXes.
For example, `apex_available: ["myapex", "otherapex"]` makes the module
available only to the two APEXes: myapex and otherapex, and nothing
else, even to the platform.

If the module is intended to be available to any APEX, then a pseudo
name "//apex_available:anyapex" can be used.

If the module is intended to be available to the platform, then another
pseudo name "//apex_available:platform" is used.

For now, if unspecified, this property defaults to ["//apex_available:platform",
"//apex_available:anyapex"], which means the module is available to everybody.
This will be reduced to ["//apex_available:platform"], when marking for
apex_available for existing modules are finished.

3aeedc9592 Do not add _platform suffix to non-apex variation
This commit renames `_platform` suffix to `` (empty string) so that
non-apex variations are not renamed to `_core_shared_platform` or
`_vendor_shared_platform`.

This commit makes sure that `_core_shared` and `_vendor_shared` is
always under `$OUT_DIR/soong` regardless the usages from apex modules.
Furthermore, this avoids the confusing stale lsdump files (e.g. both
`_core_shared` and `_core_shared_platform exist) while creating
reference ABI dumps for VNDK ABI checks.

Bug: 121986692
Test: lunch aosp_arm64-userdebug; make  # no more _platform variants.

0ddfcd1188 Don't create unnecessary APEX variations
This change fixes a problem that APEX variations are created for the
modules that actually shouldn't built for any APEX. For example,
consider this case.

apex { name: "myapex", native_shared_libs: ["mylib"],}

cc_library { name: "mylib", shared_libs: ["libfoo#10"],}
cc_library { name: "libfoo",
             shared_libs: ["libbar"],
             stubs: { versions: ["10"], }, }
cc_library { name: "libbar", ...}

Before this change, both the stubs and non-stubs variations of libfoo
were mutated with apexMuator, which is incorrect for the non-stubs
varia; there is no dependency chain from the apex "myapex" to the
non-stubs variation, but to the stubs variation due to the #10 syntax.

This was happening becauses we used the name of the module to determine
whether it should be built for APEX or not. Both stubs and non-stubs
variations have the same module name "libfoo".

Fixing this issue by recording the list of APEX variations required
directly on the module. So, the stubs variation of libfoo has myapex in
its apex variations list, but the non-stubs variation doesn't, and thus
apexMutator does not pick up the non-stubs variation.

Test: m (apex_test updated and passing)
Test: cherry-pick ag/5747464 and m

de866cbe50 Stubs dependency is not installed
When the stubs variant of a library is dependend by a platform component
and the library is included in one or more APEX, the library is not
installed to the platform, because it is provided by APEX.

Bug: 120266448
Test: m
Test: add stubs: { versions: ["1"], }, to libnetd_resolv
then build netd. libnetd_resolv.so does not exist under /system.

25fc6a9cc9 Stubs variant is used when building for APEX
When a native module is built for an APEX and is depending on a native
library having stubs (i.e. stubs.versions property is set), the stubs
variant is used unless the dependent lib is directly included in the
same APEX with the depending module.

Example:

apex {
    name: "myapex",
    native_shared_libs: ["libX", "libY"],
}

cc_library {
    name: "libX",
    shared_libs: ["libY", "libZ"],
}

cc_library {
    name: "libY",
    stubs: { versions: ["1", "2"], },
}

cc_library {
    name: "libZ",
    stubs: { versions: ["1", "2"], },
}

In this case, libX is linking to the impl variant of libY (that provides
private APIs) while libY is linking to the version 2 stubs of libZ. This is
because libY is directly included in the same apex via
native_shared_libs property, but libZ isn't.

9d45299ba4 Add ApexModule interface for APEX-aware modules
ApexModule is the interface for APEX-aware modules. The module type apex
uses the interface to get APEX-specific information from other modules,
such as the list of APEXs that a module should be built for.

A module that is included in an APEX will be built specificaly for the
APEX. This is especially required for shared libraries; we shouldn't
just copy the artifacts built for platform, because they may be linking
against private (=unstable) symbols that are not available to APEXs
which are basically unbundled.

This CL, as a first step, makes cc.Module an APEX-aware module type.

Bug: 112672359
Test: m apex.test; the built apex has all the direct and transitive
shared lib dependencies of the libs and executables listed in Android.bp
