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.

Convert .apex files to base.zip files suitable for bundletool.
They will be copied to the dist directory when built with
TARGET_BUILD_APPS and dist.
Also fix up apex.go to use Build instead of the deprecated ModuleBuild,

When TARGET_FLATTEN_APEX is set to true, APEXes are flattened, which
means files in an APEX is not packaged into the mini file system image,
but instead directly copied to the system partition.
This option is for devices where kernel does not support loopback
devices or the maximum number of loopback devices is too small (though
the threshold is TBD as of now).
This CL also fixes a bug that jars having bytecode are installed instead
of those having dex.

For centralized development of sepolices, file_contexts files for APEXes
are all moved to under /system/seplicy.
The meaning of the existing file_contexts has been changed; when it is
set to <value>, then /system/sepolicy/apex/<value>_file_contexts is
used. When unset, it defaults to the name of the module. The property is
not removed in order to support creating multiple versions of the same
apex (for testing purpose) built with same file_contexts file.

The generateFsConfig rule used to not give execution
permissions (0111) to the root (`/`) directory of the ext4 image
stored in an APEX package. This change add these bits, turning the
permissions from 0644 (drw-r--r--) to 0755 (drwxr-xr-x).
Previously, not having the execution permissions on the ext4 image's
root directory meant that the contents of the top-level directory of
the mounted image could not be listed.
Test: `adb shell ls /apex/<apex-package>` works

The properties 'binaries' and 'native_shared_libraries' can be
multilib-aware, i.e, can be under multilib.type where type can be either
first, both, lib32, lib64, or prefer32.
Native modules listed in multilib.first are installed only for the first
ABI of the device. Similarily, multilib.both are for both of the ABIs,
while multilib.lib32 and multilib.lib64 are 32 and 64-bit ABI only,
respectively. multilib.prefer32 is for 32-bit only when 32-bit ABI is
available.
Another change is that the binaries property, when not within multilib,
targets only the first ABI.
Test: m apex.test on ...
1) aosp_arm64 without TARGET_PREFER_32_BIT_EXECUTABLES=true
2) aosp_arm64 with TARGET_PREFER_32_BIT_EXECUTABLES=true
3) aosp_arm
in all cases, vold, surfaceflinger and drmserver are all intalled under
./bin directory of the APEX. And native libraries are installed under
both ./lib and ./lib64 directories in the case of 1) and 2).

The change fixes the problem that multiple APEXs having native component
(shared lib or executable) can't be built with an error similar to this:
error: bionic/linker/Android.bp:298:1: failed to find variation "com.android.art" for module "libclang_rt.builtins-aarch64-android" needed by "ld-android"
This is happening because the dependency to the built-in library is
arch-specific but apex.go ignores it. Specifically, let's assume that
32-bit variant of libFoo depends on libX while 64-bit variant of libFoo
depends on libY. Also assume that libFoo is included in two APEXs: apex1
(which is 64-bit) and apex2 (which is 32-bit). Then apexDepsMutator
records that libFoo shall be split into apex1 and apex2, while libX will
be only split into apex1 and libY will be split into apex2.
The problem is that, during apexMutator, both 32 and 64-bit varants of
libFoo are split into apex1 and apex2. As a result, a dependency to
apex2 variant of libX and a dependency to apex1 variant of libY are
requested, which don't exist.
Fixing this issue by using module's name AND target string as the key.
So, only the 32-bit variant of libFoo is split into apex1 and 64-bit
variant of libFoo is split into apex2.
Test: have following module somewhere. `m` is successful.
apex {
name: "com.android.art",
manifest: "manifest.json",
file_contexts: "file_contexts",
binaries: ["dex2oat"],
key: "apex.test.key",
target: {
android: {
// Prefer the 32-bit versions of these binaries.
compile_multilib: "prefer32",
},
},
}

A new module type 'apex_key' is defined to specify public and private
key pair for APEXs. An APEX can refer to the module via the property
'key'. When building the APEX, the private key from the key module is
used to sign it. In addition, the public key from the key module is
automatically installed to /system/etc/security/apex.

Don't directly iterate over the copyManifest map to generate the copy
commands. Iterating over a map in golang isn't guaranteed to give
consistent order. This causes the apex build rules to be executed even
when there is no source file change.
Fix the issue by creating a sorted list of the key and then iterate over
the list.

Now, APEX-aware modules (the ones implementing android.ApexModule
interface) are created with multiple variants for each APEX that they
are included.
For example, if a module is included (either directly or indirectly -
via static linking) to two APEXs, the module is built separately for the
two APEXs (and of course separately for platform). This is a first step
to limit the symbol visibility to the modules built for APEXs; platform
private symbols and libs shouldn't be allowed for them.
In addition, the build system now tracks transitive dependencies of
the modules in APEXs. For example, if
native_shared_lib_modules:["libFoo"] then libFoo and its dependencies
are all automatically included to the APEX.
Bug: 112672359
Test: m apex.test; the built apex has additional libs (such as liblog,
