715cac3971 Optimizations to abi checking.
We now add export_static_lib_headers, export_generated_headers to the
filters while dumping the abi of a library using header-abi-dumper
(through -I<dir> additions to the invocation of header-abi-dumper and
header-abi-linker)

Also add support for zipped reference source based abi dumps.

Test: mm -j64 in hardware/interfaces/nfc/default/1.0 produces
android.hardware.nfc@1.0.so.lsdump with abi filtered out using generated
headers.

Test: Copied the linked abi dumps produced by mm -j64 in bionic/libc to
prebuilts/abi-dumps/ndk and gzipped them. Ran mm -j64 again in
bionic/libc and verified header-abi-diff getting invoked.

10d2231d44 Check reused source files in hasSrcExt
hasSrcExt is used to determine extra flags and dependencies when
generated files are used.  If the generated files are being handled
in a static library whose objects are reused in a shared library,
the flags and dependencies still need to apply.  Instead of clearing
the source files in the shared library, move them to an OriginalSrcs
property, and check that in hasSrcExt along with the Srcs property.

Also pass extra exported include directories from the static
library to the shared library.

3e231fd8bd Add header-abi-checker for Vndk abi checks.
header-abi-dumper: dumps abi exported by source files for Vndk.
header-abi-linker: links abi dumps produced by header-abi-dumper.
header-abi-diff: compares linked dumps.

Test: mm -j64 showcommands > make_log in bionic/libc.
      This produced linked dumps in out/soong/.intermediates.
      Copied these dumps to
      prebuilts/abi-dumps/ndk/current/arm64/source-based/.
      Changed the abi and re-ran mm -j64 showcommands > make_log
      confirmed that the build reported compatibility breakge without
      actually failing (advisory mode).

4416e5db69 Split /system and /vendor modules, allow multi-installation
Nothing changes if BOARD_VNDK_VERSION isn't set.

When the VNDK is enabled (BOARD_VNDK_VERSION in Make), this will split
/system and /vendor modules into two different variant spaces that can't
link to each other. There are a few interfaces between the two variant
spaces:

The `llndk_library` stubs will be available in the /vendor variant, but
won't be installed, so at runtime the /system variant will be used.

Setting `vendor_available: true` will split a module into both variants.
The /system (or "core") variant will compile just like today. The
/vendor ("vendor") variant will compile against everything else in the
vendor space (so LL-NDK instead of libc/liblog/etc). There will be two
copies of these libraries installed onto the final device.

Since the available runtime interfaces for vendor modules may be
reduced, and your dependencies may not expose their private interfaces,
we allow the vendor variants to reduce their compilation set, and export
a different set of headers:

  cc_library {
      name: "libfoo",
      srcs: ["common.cpp", "private_impl.cpp"],
      export_include_dirs: ["include"],
      target: {
          vendor: {
	      export_include_dirs: ["include_vndk"],
	      exclude_srcs: ["private_impl.cpp"],
	      srcs: ["vendor_only.cpp"],
	  },
      },
  }

So the "core" variant would compile with both "common.cpp" and
"private_impl.cpp", and export "include".

The "vendor" variant would compile "common.cpp" and "vendor_only.cpp",
and export "include_vndk".

1dd8839286 Refactor sanitized library on-disk layout - Soong.
This CL moves the location of ASAN-ified libraries on disk in the
following manner:
/data/lib* --> /data/asan/system/lib*
/data/vendor/* --> /data/asan/vendor/*

There are a couple of advantages to this, including better isolation
from other components, and more transparent linker renaming and
SELinux policies.

Bug: 36674745
Test: m -j40 && SANITIZE_TARGET="address" m -j40 and the device
boots. All sanitized libraries are correctly located in /data/asan/*.

01a405a481 Add LinuxBionic toolchain and switch
This adds a toolchain definition for LinuxBionic that only supports
Clang/64-bit. It pulls pieces from the x86_linux_host and x86_64_device
configs, and uses the android clang triple, with some manual overrides.

To enable building this, set your soong.config file to:

 {"Host_bionic": true}

4c48f724e1 install *.so in different paths for their types
Shared libraries are now installed to different directories depending on
their types.

* NDK libraries: /system/lib/ndk
* VNDK libraries: /system/lib/vndk
* VNDK-ext libraries: /system/lib/vndk-ext
* Framework-only libraries: /system/lib
* Vendor-only libraries: /vendor/lib
* Same-process HALs: /vendor/lib/sameprocess

In addition, a new module type vndk_ext_library is added. It is almost
identical to cc_shared_library but it introduces another attribute
'extends'. This is use to reference the vndk library that this vndk-ext
library is extending.

For example, in order to extend a vndk library libFoo:

cc_library {
  name: "libFoo",
  srcs: [...]
}
---------------------
vndk_ext_library {
  name: "libFoo-extended",
  srcs: [...]
  extends: "libFoo"
}

Then, libFoo will be installed as /system/lib/vndk/libFoo.so and
libFoo-extended will be installed as /system/lib/vndk-ext/libFoo.so.
Note that file name of the latter is libFoo.so, not libFoo-extended.so:
file name of an extending module is automatically set to that of the
extended module.

a48ab5b207 Build a static library for header-only libraries
library.static() was being used to determine if a library was static,
shared, or header only, which resulted in header only libraries
behaving like shared libraries, when they should be treated as static
libraries with no sources.  Explicitly use library.static(),
library.shared(), and library.header() instead.

581341d4f2 Native Coverage support in Soong (gcov)
This is configured the same as make -- a global NATIVE_COVERAGE=true
flag to allow native coverage, then COVERAGE_PATHS=path1,path2,... to
turn it on for certain paths.

There are .gcnodir files exported to Make and saved in $OUT/coverage/...
files which are `ar` archives containing all of the compiler-produced
.gcno files for a particular executable / shared library.

Unlike the Make implementation, this only passes links the helper
library (automatically through --coverage) when one of the object files
or static libraries being used actually has coverage enabled.

Host support is currently disabled, since we set -nodefaultlibs, which
prevents libclang_rt.profile-*.a from being picked up automatically.

Bug: 32749731

d2ede879b5 Add basic VNDK support in Soong
Export a list of libraries in the VNDK, which is currently empty.

Take in Make's global BOARD_VNDK_VERSION, and use that as the SDK
version for modules that specify use_vndk: true.

Modules that use the vndk have some configuration as if they were
building against the NDK (the absence of globally defined headers), but
in other cases look like platform modules (using the platform libc++,
for now).

This change does not attempt to enforce any linking constraints, that
will come in a later patch.

a03cf6d322 Add clang-tidy support
For every file which we can run clang-tidy (C/C++ clang-built), we add a
new build node that depends on the object file (since clang-tidy does
not export a depfile), and is depended on by the link step. This is
better than how we're doing it in make, since calling tidy can be turned
on or off without needing to rebuild the object files.

This does not attempt to port WITH_TIDY_ONLY from Make, since the way
that it works is broken (due to the lack of a depfile).

89562dc308 Enable toc optimization for host builds
The toc optimization had been disabled for host builds to ensure that
the timestamp of the final binary changed whenever its implementation
changed, in order to support rerunning host tools that were modified
during incremental builds.  However, only the final install rule must be
re-run to update the timestamp, and not the link rule.

Update the shared library install dependencies to use normal
dependencies instead of order-only dependencies for host modules, and
then enable the the toc optimization for host modules.  If the
implementation of a library changes it will be reinstalled, and
libraries or binaries that depend on it will also be reinstalled.

Also move toc generation to happen on the packed, stripped library,
which is what will be used for linking, to ensure that it is available
at link time when depending only on the toc file.
