This commit adds a header_abi_checker section so that the library owner
can have a fine-grained control over the ABIs that must be checked.
For example, a library "libexample" may have following configurations:
cc_library {
name: "libexample",
header_abi_checker: {
symbol_file: "libexample.map.txt",
exclude_symbol_versions: ["LIBEXAMPLE_PRIVATE"],
exclude_symbol_tags: ["platform", "apex"],
},

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

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

Historically, we've always passed '-I .' as the first argument to
protoc, essentially treating all proto file package names as their full
path in the android source tree. This would make sense in a monorepo
world, but it makes less sense when we're pulling in external projects
with established package names.
So keep the same default (for now), but allow individual builds to opt
into using local paths as the default names with
'canonical_path_from_root: false'. A cleanup effort and/or large scale
change in the future could change the default to false.
As part of this, run protoc once per input proto file, since the flags
may need to change per-file. We'll also need this in order to specify
--dependency_out in the future.

This commit adds `extends: "name"` property and provides basic support
to VNDK extensions. This is the simplest example:
```
cc_library {
name: "libvndk",
vendor_available: true,
vndk {
enabled: true,
},
}
cc_library {
name: "libvndk_ext",
vendor: true,
vndk: {
enabled: true,
extends: "libvndk",
},
}
```
A vndk extension library must extend an existing vndk library which has
`vendor_available: true`. These two libraries must have the same
`support_system_process` property.
VNDK-ext libraries are installed to `/vendor/lib[64]/vndk` and
VNDK-SP-ext libraries are installed to `/vendor/lib[64]/vndk-sp` by
default.
If there is a matching abi-dumps in `prebuilts/abi-dumps`,
`header-abi-diff` will be invoked to check for ABI breakages.

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

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.

When the UseGoma flag is set, put all rules except the C compilation
rule in an externally defined local_pool, which will have been created
by kati. The gomacc wrapper will already be in the CC_WRAPPER
environment variable.

We're already referring to the library by the full path. The -L is
unnecessary.

Test: Still builds.

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.

On Darwin ar would fail if there is no object file to add.
We work around by adding a dummy.o.

The strip tool is different on Darwin, use a separate darwinStrip rule
instead of calling strip.sh for host builds on Darwin.

Strip all shared libraries and binaries by default. Use a shell script
to wrap the long sequences of commands needed by some strip variants.

Add a new feature to cc modules that adds the cflags and libraries
necessary to implement AddressSanitizer, ThreadSanitizer, and
UndefinedBehaviorSanitizer.

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 roughly matches what make uses, but with less string parsing.
Also use a full path to "ar", so that we can depend on it.

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.

This defines another mutator between HostOrDevice and Arch that will
expand host modules into a module for each host type
(Darwin/Linux/Windows) that is currently being built.

x86 crt partial ld steps need to pass -m32 through ldflags. Use gcc to
run partial ld instead of going directly to ld. Allows reusing
ToolchainLdflags, which have linker arguments prefixed with "-Wl,".

This uses the new CommandDeps field to move implicit dependencies
embedded in the Command string next to the definition, instead of having
to specify them in every BuildParam struct. This should make it easier
to verify dependencies.

We cannot use the PWD trick for any compile on Darwin, since /proc
doesn't exist. So instead of checking for darwin host modules, just
check runtime.GOOS.
And since this isn't a per-module decision, don't pass it along as a
variable to every build command, but make it a global variable.

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.

ccCmd was being added as a dependency each time through the object
file loop, tripling the size of the build.ninja file. Create a
new slice for dependencies on each object file.

Reduce the number of flags variables when compiling C by getting
rid of the separately-tracked IncludeDirs variables, and putting
them directly in GlobalFlags. Also changes exportedIncludeDirs
to exportedFlags, which will allow exporting flags besides -I.
Also fixes a bug when building a module with the NDK and -Werror
by passing NDK exported include directories with -isystem instead
of -I, which will ignore warnings from those includes.
Also fixes a bug where the default includes were being inserted
into all cflags by the arm and arm64 toolchain modules.

Using ctx.Config().(Config) everywhere is a mouthful, and it is
inefficient to do the type assertion. Put the Config interface into
the context, and provide an AConfig() to return the Config already
converted to the right type.

Add support for yacc (.y or .yy) and lex (.l or .ll) files. Also
tweak locations of .o files for normal and generated sources to
makes sure they don't collide.

ld and ar command lines often end up larger than ARG_MAX, use Ninja's
rsp file support to automatically write the object files to a temporary
file and pass it in using @file support.
This isn't going to work on Darwin host builds, where the host
toolchains don't support @.

The linker needs to add __dl_ to the beginning of all of its symbols
to avoid conflicts. Add support for a prefix_symbols property, and
insert an objcopy --prefix_symbols build step to produce the final
binary.

ccLibrary uses ccDynamic for linking shared libraries, but bypasses
it by calling directly into ccBase for static libraries. Instead of
duplicating the same mess for ccBinary, rename ccDynamic to ccLinked
and add the logic for dealing with static or shared linkage. This
also allows moving the stl logic out of ccBase and into ccLinked.

Art needs a custom module type in order to perform complicated
build logic like depending on environment variables and varying
cflags based on cpu variant. Export enough of the types and
functions from cc for art_cc_library to inherit from cc_library.
While I'm touching every line, also rename the New* methods
to *Factory.
