Prototypes in the bionic headers are annotated with `__INTRODUCED_IN`
tags that are processed by bionic/tools/versioner into their usable
form (tags replaced with `#if __ANDROID_API__ >= foo` guards). We've
previously done this as a periodic manual step with the results
checked in to prebuilts/ndk, but that's been a huge hassle for me.
Make the tool a part of the build instead.

Adds the -fsanitize-blacklist option for CFI, using the built in
blacklist at external/compiler-rt/lib/cfi/cfi_blacklist.txt.
Also refactors the CFI cflags and ldflags into cc/makevars.go to
ensure they're consistent across Soong and make projects.

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.

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.

Allow tests to specify a data property that lists files or filegroup
modules that will be packaged alongside the test. Also add a path
property to filegroup modules to allow shifting the path of the
packaged files, and add ExpandSourcesSubDir to expand the filegroup
sources while including a shifted relative path in the Paths objects.
Test: soong tests, manually adding data to a module

-pie triggers a bug in glibc's linker when used with goma
(https://sourceware.org/bugzilla/show_bug.cgi?id=16381). Allow
the clang build to disable -pie for host modules through the
DISABLE_HOST_PIE environment variable so it can produce a toolchain
that works with goma.

The linker uses libc++_static but needs to avoid the libc.a
dependency. It does this by setting `stl: "none"` and manually
linking libc++. This behavior matches make.
A better approach would probably be to generalize system_shared_libs
to system_libs and apply those to static executables the same way we
do for dynamic ones, but that's a patch for another day.

c++_shared and c++_static are named libc++ and libc++_static in every
other mode. Allow the same names so targets which are built for both
host and device with SDK may specify a single name for the STL.
Test: external/boringssl is able to use "libc++_static" as the STL.

Since most system libraries aren't actually versioned yet, we
shouldn't be building the stub libraries with version info just yet.
Setting `unversioned_until: "current"` will not use the version
script for anything but android-current (this way when the version
script is applied, we'll immediately catch it if they don't match).
Test: Updated frameworks/wilhelp to use this, make ndk

Some external test suites (LTP in this case), have their own expected
layout, and don't fit well with our
/data/nativetest/<testname>/<testname> layout, nor do they work with
test_per_src.
So allow setting no_named_install_directory along with
relative_module_path to specify a custom test path:
no_named_install_directory: true,
relative_module_path: "ltp/testcases/bin",
