Some tools (i.e. you-complete-me) make use of a 'compdb' file
(compile_commands.json) that records (among other things) the
arguments needed to compile a file. These tools can use this with
libclang to provide semantic completions and perform other IDE
actions. This CL adds support for soong to generate a (simple)
compile_commands.json file.

Test: make SOONG_GEN_COMPDB=1 SOONG_LINK_COMPDB_TO=$ANDROID_BUILD_TOP nothing
      examine $ANDROID_BUILD_TOP/compile_commands.json

java_sdk_library is to make a Java library that implements optional
SDK APIs to apps. It is actually a wrapper for several modules: 1) stubs
library that clients are linked against to, 2) droiddoc module that
internally generates API stubs source files, 3) the real runtime shared
library that implements the API, and 4) XML file for adding the runtime
lib to the classpath at runtime if requested via <uses-library>.

Note: this is only the initial CL for the feature. Followings are features
currently missing and under development.

1) check for API consistency
2) install stubs libs as the dist artifacts
3) ensuring that apps have appropriate <uses-library> tag
4) disallowing linking to the runtime shared lib
5) HTML generation

aapt2 --min-sdk-version was using AppsDefaultVersionName(), which
is OMR1 for a non-finalized SDK, but 8.1.0 after finalization.

- Allow filegroup's properties to be extended by a LoadHook
- Support a filegroup (':module') in a prebuilt's 'Srcs' property to
export files from a different path as the prebuilt's sources.

This change also includes a refactoring that moves genrule/filegroup.go
to android/filegroup.go so that FileGroupFactory is visible in
prebuilt_test.go.

LOCAL_RESOURCE_DIRS puts the highest priority overlay first, but
aapt2 expects the highest priority overlay last.  Soong stores the
list in aapt2 order (low to high priority), but that means when it
exports to Make as LOCAL_SOONG_RRO_DIRS, which goes to
build_rro_package.mk and then package_internal.mk, it gets reversed
again and comes out backwards.

When we're doing ABI diffing, we run something like:

  (run-abi-diff) || (echo && exit 1)

When `dist` is added, we attempt to copy out the result:

  (run-abi-diff) || (echo) && (copy && exit 1)

But this always fails, since it will always run exit 1. We really want
the parenthesis around the entire second section. This change switches
it to:

  (run-abi-diff) || (echo && (copy) && exit 1)

This matches the behavior before Iae25374fe937a0cbe8a8ddf9e23c3bc1f62bbb2a

* USE_CLANG_LLD is unedefined in current builds.
* When USE_CLANG_LLD is defined to 'true' or '1',
  use clang's lld instead of ld or ld.gold.
* When lld is enabled:
  * ld-only flags are not passed to 'lld'.
  * location_packer is disabled.
  * Use new lld's --pack-dyn-relocs=android.
* When lld does not work:
  * In Android.mk files use LOCAL_USE_CLANG_LLD := false.
  * In Android.bp files use use_clang_lld: false.
* Only arm, arm64, x86, and x86_64_devices have LLD flags;
  all other hosts and targets do not call lld yet.
