This adds the `versioned=API` tag. This should be a very uncommonly
needed tag, and is really only needed to fix versioning mistakes that
are already out in the wild.
For example, some of libc's __aeabi_* functions were originally placed
in the private version, but that was incorrect. They are now in
LIBC_N, but when building against any version prior to N we need the
symbol to be unversioned (otherwise it won't resolve on M where it is
private).
Test: make ndk

A version block might need to be omitted for reasons beyond just
"future". Support all the same tags we do at symbol scope.
Test: `make ndk` with libc/libm migration patches.

Symbols that have been added to a library but should not be exposed
in any of the current NDK API levels should be tagged with "future".
These will be suppressed from the NDK libraries.
Once all this is in better shape we'll have `sdk: "current"`. Symbols
tagged with "future" will be available for that.
Note that this tag can be applied directly to a version. Aside from
being more ergonomic than tagging an entire section, this also solved
the problem of gen_stub_libs.py emitting an empty global section
(which is not valid syntax) in the case where every symbol is
"future". Tag the version instead and it will be omitted.
Test: `make ndk` with libc/libm migration patches.

The list of migrated libraries is currently empty. Libraries will be

build.ninja shows libraries being built and used and headers are

The Customizer interface now provides a Flags method that takes a
CustomizerFlagsContext and can call AppendCflags to insert extra cflags
on a module.

When these are Ninja variable they can't be used in android.Path since
they'll be rejected as invalid paths. We don't actually need them to be
a Ninja variable, so make them plain old strings instead.

libnativehelper has an Android.bp file, so it won't cause a namespace

To allow cflag changes when using the "old" binder API that are still
used by all 32-bit only configurations. We can't just use
android32/android64 here, since some devices use a 64-bit kernel with a
32-bit userspace, which is configured as "android32".

In order to distinguish our host libraries from system installed
libraries, support a flag to automatically append -host to host shared
libraries names. Previously, we were implementing this with different modules,
but with Soong, we'd really like to share the module definitions.
This properly exports the module to make, so that
LOCAL_SHARED_LIBRARIES := libcrypto still works, but the final installed
name is libcrypto-host.so.

Bionic includes are the same on all architectures, modulo
architecture-specific includes. Use a single function to populate the
list, passing in bionic's and the kernel's names for the architecture.
Also get rid of the ${LibcRoot} variable, it is not providing any value
and makes grepping harder.

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.
