8e4d371091 Add greg_t for arm64.
This was already present for the other architectures. I think we skipped
this because glibc seems to have an incorrect definition (int rather than
long), but the kernel has the sane definition (just not in a uapi header).

ba8d4f460b Update kernel uapi headers to v3.16.1.
Other changes to support the new headers:

- Remove the flock64 structure it is defined in the new headers.
- Update the syscalls to correspond with the headers.

26a8eb50a8 POSIX says <signal.h> gets you ucontext_t.
POSIX also says that ucontext_t's uc_sigmask has type sigset_t.

MIPS64 strace needs this.

The #define is to keep chromium off our lawn; otherwise it tries to redefine
all this stuff itself. We should probably clean that up and remove the #define.

a4831cb4a3 Add pthread_gettid_np and re-expose __get_thread for LP32.
A lot of third-party code calls the private __get_thread symbol,
often as part of a backport of bionic's pthread_rwlock implementation.
Hopefully this will go away for LP64 (since you're guaranteed the
real implementation there), but there are still APIs that take a tid
and no way to convert between a pthread_t and a tid. pthread_gettid_np
is a public API for that. To aid the transition, make __get_thread
available again for LP32.

32429606bf Make stdatomic.h work with gcc4.6 host compiler
This is needed to make L work correctly, and bionic tests pass
again, after applying the equivalent of
commit 00aaea3645 there.

It makes the preexisting code that uses __sync implementations
much more useful, although we should no longer be exercising that
code in AOSP.

Specifically fixes:

We were invoking __has_extension and __has_builtin for GCC compilations.
They're clang specific. Restructured the tests.

The __sync implementation was not defining the LOCK_FREE macros.

ATOMIC_VAR_INIT was using named field initializations.  These are a
C, not C++, feature, that is not supported by g++ 4.6.

The stdatomic bionic test still failed with 4.6 and glibc with our
questionable LOCK_FREE macro implementation.  Don't run that piece
with 4.6.

In L, this is a prerequisite for fixing:

416d7ddaff Add GNU-compatible strerror_r.
We already had the POSIX strerror_r, but some third-party code defines
_GNU_SOURCE and expects to get the GNU strerror_r instead.

This exposed a bug in the libc internal logging functions where unlike
their standard brethren they wouldn't return the number of bytes they'd
have liked to have written.

b6b5cb5389 Ignore all __weak_alias in OpenBSD libC.
GCC assembler allows xyz to be redeclared as weak,
by __weak_alias(xyz, _xyz), while _xyz is undefined.
Clang does not like that but silently generates no code.
It will reject its own .s file if the assembly code is saved first.
Since we have no reason to define xyz or _xyz as weak symbol now,
and _xyz is a macro to xyz, we simplify libC to have only
xyz defined as global.

3e4a0099a1 Undefine _Atomic before redefining
Stdatomic.h was potentially redefining _Atomic, in spite of a
prior definition by <atomic>.  This could cause g++ builds that
included <stdatomic.h> with an available <atomic> header to break.

00aaea3645 Fix, generalize stdatomic.h; improve test.
We seem to use this stdatomic.h sometimes, and slightly different prebuilts
at other times, making them all difficult to test, and making it unclear
which one we're testing.  This generalizes the bionic header so that it
can be used directly as the prebuilt header as well.  So long as they
don't diverge again, that should somewhat improve test coverage.

Use the correct builtin for atomic_is_lock_free.

Fix atomic_flag_init.

Turn on atomic tests even with __GLIBC__, since they now appear to pass.

Include uchar.h in stdatomic.h where needed.

Add a basic memory ordering test.

Fix bit-rotted comments in bionic tests makefile.

35d226e05d Add in_port_t and move it and in_addr_t to the correct header file.
No one's reported this, but I saw it in an Android port of fuser(1).

We still have lots of problems in our network headers because we
get most of the structs direct from the kernel, and it doesn't use
types like this (which is why we've got away without this one for
so long). One day we should probably look at cleaning that up, but
doing so can wait.

5f5cc45cf0 Fix <features.h> (_BSD_SOURCE and _GNU_SOURCE).
<features.h> is supposed to take user-settable stuff like _GNU_SOURCE
and _BSD_SOURCE and turn them into __USE_GNU and __USE_BSD for use in
the C library headers. Instead, bionic used to unconditionally define
_BSD_SOURCE and _GNU_SOURCE, and then test _GNU_SOURCE in the header
files (which makes no sense whatsoever).

Lose three dead files from the DNS code.

Hans Boehm
019d395811 Have stdatomic.h punt to C++ atomic when possible
This is an alternate, somewhat simpler, fix that makes it safe to
include both <atomic> and <stdatomic.h> from C++ code in either order.
It means that C code consistently uses one implementation of atomics
and C++ another.  We still have to make sure that those two
implementations interoperate correctly at runtime; in particular,
any flavor of atomic object needs to be represented exactly like the
underlying type, with the proper alignment constraint.
