Add a list of flags which are not understood by clang LibTooling tools
and filter them out of the Cflags the tools are invoked with.
Test: In frameworks/av, make libmedia vendor_available (this invokes
header-abi-dumper on this module), mm -j64.

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).

Include order should be module includes, dependency exported includes,
and then global includes. Module includes and global includes are
computed during compileFlags, but dependency exported includes are
not handled until later. Move the global includes into a new
flags variable so that the dependency includes can be appended
to the module includes.
Test: m -j native

Adds the ability to set custom flags for ar in Soong, similar to how
they can currently be set for make.
Bug: 36290748
Test: sanitize.go is able to correct set custom ar flags for CFI. CFI
enabled Soong components build and boot without issue.

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
Test: NATIVE_COVERAGE=true COVERAGE_PATHS=system/core/libcutils m -j libbacktrace libutils tombstoned
$OUT/coverage/system/lib*/libcutils.gcnodir looks correct (self)
$OUT/coverage/system/lib*/libbacktrace.gcnodir looks correct (static)
$OUT/coverage/system/lib*/libutils.gcnodir doesn't exist (shared)
$OUT/coverage/system/bin/tombstoned.gcnodir looks correct (executable)
Test: NATIVE_COVERAGE=true COVERAGE_PATHS=external/libcxxabi m -j libc++
Confirm that $OUT/coverage/system/lib*/libc++.gcnodir looks correct (whole_static_libs)

Ideally we'd calculate the headers that are written here too, but I'll
add that in a later change that actually enforces the generated header
list.

LLVM has complicated static library layering that sometimes changes.
The make solution was to list all the static libraries twice, but
Soong dedups the list. Add a group_static_libs flag to allow
surrounding the static libs with -Wl,--start-group and
-Wl,--end-group.
Test: mmma -j external/llvm

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).
Bug: 32244182
Test: WITH_TIDY=true mmma -j bionic/libc
Test: ./soong (Setting ClangTidy: true)

.proto files are translated to .pb.cc and .pb.h files, which are then
compiled normally.

Some checks for common errors with user-provided compiler and linker
flags:
* Using -I instead of include_dirs
* Using -l<lib> in ldflags instead of host_ldlibs (or shared_libs)
* Using -L in ldflags
* Splitting a multi-word flag into two flags
* Combining two flags into one list entry
* Using a path that could search outside the source or output trees
* Using a non-whitelisted library in host_ldlibs
Maybe some of the flag checks should happen during a static analysis
pass, but we don't have one right now, and this only adds ~1/2 second to
our 73 second Mega_device runs (recompile the changed code, run
soong_build, then report unknown target).

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

the arch variant against supported versions.

Refactor all of cc in order to use composition instead of inheritance.
All cc module types exported by cc are now *cc.Module objects, with
compilation, linking, and installing steps delegated to different
objects in order to form the full module type. Additional features that
modify dependencies and flags can be inserted in a features object list,
and custom module types can be created by adding a Customizer object
that can modify properties.

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.

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.

an aidl_preprocess module type for framework and sdk aidls.

tweak locations of .o files for normal and generated sources to
makes sure they don't collide.

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.
