Clang does not output file dependencies from the -fprofile-use= flag

Convert abi warnings to errors by removing the -advice-only flag from
the invocation of header-abi-diff. This will only apply to branches with
reference abi dumps checked into prebuilts/abi-dumps/(v)ndk (since
abi-diffing will only be triggered on them.)
Also allow for:
1) Extensions.
2) Changes to types in exported headers, unreferenced by public symbols still
trigger warnings.
3) Any removal of symbols appearing in a shared library's .dynsym table, but not
in exported headers is still a warning.

Now that android.ModuleContext does not include blueprint.ModuleContext

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

Include order should be module includes, dependency exported includes,
and then global includes. Module includes and global includes are

to the module includes.

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.

LLVM has complicated static library layering that sometimes changes.

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).

Using only -lc (for example) means that in the case where we have one
library path with libc.a but no libc.so (such as prebuilts/ndk) and
another with libc.so (such as the out directory), we'll always use the
static version.
We can link shared libraries by their full path to be sure that we
always get the right library.

Add two cc properties: `generated_sources` and `generated_headers`,
instead of just adding genrule modules to `deps`. Label these with the
dep tagging mechanism, add the generated_headers paths to the include
paths, and add dependencies to generated headers for each compile.
Add dependencies so that regular sources can include generated yacc
headers, not just other generated lex/yacc files. Static/shared specific
sources still don't have dependencies to or from regular sources though.
Switch from an implicit dependency on generated files to an orderonly
dependency, since the depfile will take care of the necessary implicit
dependencies for incremental builds.

This centralizes verification and common operations, like converting the
path to a source file to the path for a built object.
It also embeds the configuration knowledge into the path, so that we can
remove "${SrcDir}/path" from the ninja file. When SrcDir is '.', that
leads to paths like './path' instead of just 'path' like make is doing,
causing differences in compiled binaries.

The existing behavior of using the build directory as the working
directory is useful if you want to move/copy the output directory around
and SRCDIR still refers the the source. But, it's more useful to have
the source directory be the working directory. Tools like cpp(__FILE__)
and other debug prints embed relative paths from the working directory.
We also have tools that expect the working directory to be $TOP.

Reduce the number of flags variables when compiling C by getting
