c1b4476808 fdsan: make the tag type values sequential.
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.

99d54656bd Add PR_SET_VMA and PR_SET_VMA_ANON_NAME to <sys/prctl.h>.
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.)

c1c8a188b2 Fix arm32/64 dynamic TLS relocations
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 It's been replaced by R_ARM_TLS_DESC, a dynamic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

7763ab4bcb Use the FreeBSD __CONCAT.
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.

ab52807685 Update to FreeBSD libm r336665.
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.

067bdc9546 Retire GCC FORTIFY.
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.

I don't think this will help the original submitter, because <resolv.h>
is mostly useless on Android. One day we might have a deprecation and
removal policy for the NDK, but until then we should probably maintain
this header.

6c0eab9c5b Include uchar.h only for bionic
Bug: http://b/111265772

uchar.h is not available in the glibc used for the host.  Since Bionic's
stdatomic.h is also used for the host (via a copy in prebuilts/clang)
guard the include with a check for __BIONIC__.

Also replace the check for C11 around definition of
atomic_char_{16,32}_t with a check for __BIONIC__.  While we're here,
check if __cplusplus is defined before checking its value.  This avoids
a potential -Wundef warning.

POSIX says ftw/nftw "shall fail" in various cases where BSD's fts_open
doesn't. Since our ftw/nftw are written in terms of fts_open, add a back
