musl libc doesn't provide fts, but elfutils and libabigail need it.
Export bionic's fts as a staic library that can be linked into elfutils
and libabigail when compiling against musl.
fts uses recallocarray, which musl doesn't provide, so also include
recallocarray.c in libfts.a.
Requires minor tweaks to fts.c and a wrapper around fts.h to make them
compatible with musl, primarily by providing local definitions of macros
provided in bionic's sys/cdefs.h.

fts.c is from openbsd and has compatibility macros to make it compile
as part of bionic. Move it into libc_openbsd_ndk where it will
get the workarounds from -include openbsd-compat.h instead.

(cherry picked from commit 61a5a8380d)
Use target.bionic.system_shared_libs when it is used to limit the
default shared libraries (as opposed to remove them completely).
This avoids attempting to add a host dependency on libc when
system_shared_libs is modified to apply to all variants.

Remove the vestigial llndk_library and replace it with properties
in the llndk clause of the implementation cc_library.
In order to reduce duplication of the arch-specific headers used
by the implementation and LLNDK, rename libc_headers_arch to
libc_llndk_headers and hoist the "include" directory out of it,
since that directory is preproccessed separately for LLNDK
libraries.

Change 75830fb836 to fix _nres
initialization to be thread safe accidentally introduced a behavior
change whereby res_init() became a no-op. It also failed to remove all
direct accesses to _nres.
Move the file over to C++ so we can let RAII ensure we're always holding
a lock while using the global state, make all callers access the global
state via this class, and restore the previous behavior of res_init().

Currently there is a pattern of `crtbegin_${type}1` and `crtbegin_${type}` modules, where the former
has sources and the latter depends on the former. The two modules for a type share many properties,
rather than duplicating these, we merge modules, such that each type only has a `crtbegin_${type}`
module.

Binaries defined in Makefiles that use the SDK need a variant to link

Bug: http://b/157081822
If __libc_int0x80 is in a C/C++ file, Clang's coverage instrumentation
adds instructions to count the number of times it gets executed [1].
With coverage instrumentation, __libc_sysinfo, used on 32-bit x86, is
initialized to the wrong value, causing dl.preinit_system_calls to fail.
Moving the function to an assembly file leaves __libc_sysinfo properly
initialized.
[1] We could change clang so it doesn't instrument functions marked
__attribute__((naked)) as a followup.

For backwards compatibility (e.g. with old apps), arm32 libc.so and
libm.so export some of the builtins. On 32-bit x86, libc.so also
exports some of the builtins.
The non-exported variant of the builtins will eventually have hidden
symbols but doesn't currently because D93431 hasn't been merged into
our toolchain yet. See:
