* changes:
libc: Match header annotations to version script
versioner: Build SymbolDatabase from version scripts
versioner: Add 28 to version list
libc: Add default __STRING implementation
According to `libc.map.txt`, `pselect64()` was introduced since API
level 28. This commit adds the annotations to `sys/select.h`.

This commit defines a default `__STRING()` definition. There should be
a default definition because the unit test cases of versioner will
include `android/versioning.h` directly. We cannot include
`sys/cdefs.h` in `android/versioning.h` either because that will lead to
circular inclusion.

glibc and musl both have these as synonyms for one another, so we may
as well do the same and get backwards compatibility on old OS releases.

In retrospect, allocating tag types from both ends will just make the
future creation of user-defined tags harder, because constants that are
introduced, and then used in previous versions might collide with
user-defined tags. Move all of the tag values to the front, so that we
can allocate from the end to minimize this.

Make it easier to write tests in users of fdsan by exposing functions

We've copied & pasted these to too many places. And if we're going to
have another go at upstreaming these, that's probably yet another reason
to have the *values* in just one place. (Even if upstream wants different
names, we'll likely keep the legacy names around for a while for source
compatibility.)

arm32: Add a relocation for TLS descriptors (e.g. gcc's
-mtls-dialect=gnu2).
arm64: Add all the dynamic TLS relocations.
Two of the relocations here are obsolete:
- ARM documents R_ARM_SWI24 as an obsolete static relocation without
saying what it did. It's been replaced by R_ARM_TLS_DESC, a dynamic
relocation. We could probably remove it, but I left it because arm32
is old, and I see the macro in other libc's. It's probably analogous
to R_ARM_THM_SWI8, which is also an obsolete relocation reserved for
a future dynamic relocation.
- I couldn't find any ARM documentation at all for
R_AARCH64_TLS_DTPREL32. It seems to have been part of three
relocations:
- R_AARCH64_TLS_DTPREL32 1031
- R_AARCH64_TLS_DTPMOD32 1032
- R_AARCH64_TLS_TPREL32 1033

We had the NetBSD __CONCAT macro, despite the fact that our only callers
are FreeBSD code. The FreeBSD libm changes in FreeBSD r336665 require
the FreeBSD implementation rather than the NetBSD one.
Unfortunately for me, that libm code is built in the NDK build too,
where it's built against the NDK's <sys/cdefs.h>. So I need to update
__CONCAT first before I can update the libm code.

This reverts commit 067bdc9546.
The angler/bullhead builds still use GCC, so I'll wait until they're turned down.

This reverts commit 253a830631 and moves
us forward to a revision that contains fixes for the problem with the
previous attempt.
This also makes sincos(3)/sincosf(3)/sincosl(3) available to `_BSD_SOURCE`
as well as `_GNU_SOURCE`.
The new FreeBSD libm code requires the FreeBSD `__CONCAT` macro, and all
our existing callers are FreeBSD too, so update that.
There's also an assumption that <complex.h> drags in <math.h> which isn't
true for us, so work around that with `-include` in the makefile. This
then causes clang to recognize a bug -- returning from a void function --
in our fake (LP32) sincosl(3), so fix that too.

NDK r18 (which removes GCC) is about to ship. We don't need this any more.
The immediate motivation for removing this right now is that the test
fails whenever we add Clang-only flags to the build system.
While we're here, clean up <stdatomic.h> too.
