55ee845b8e Inline helpers need to be exported unmangled.
__open_2() is used by the fortify implementation of open(2) in
fcntl.h, and as such needs an unmangled C name. For some reason
(inlining?), this doesn't cause problems at the default optimization
level, but does for -O0.

The rest of these didn't cause build failures, but they look suspect
and probably will, we just haven't caught them yet.

(cherry-pick of 658727e111ed6dee7be5239494f0764f7b1b02f8 with conflicts
in stdio.h and string.h.)

ce92b41a00 cdefs.h: add artificial attribute to FORTIFY_SOURCE functions
Otherwise the gcc compiler warning doesn't show up.

Add -Wno-error to fortify related tests. Fortify related tests
are expected to be examples of bad programs, and in many
cases shouldn't compile cleanly. Rewriting them to compile
cleanly isn't feasible nor desirable.

d87d401ab1 Improve <sys/cdefs.h>.
Fix and use __RENAME (and lose ___RENAME --- two underscores should be
enough for anybody). This was the point of this change, because I want
to use __RENAME to support the two basename variants and the two
strerror_r variants.

Lose a bunch of macros that weren't being used.

Lose three dead files from the DNS code.

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).

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.

9ac60bf82b Make stdatomic.h work with gcc4.6 host compiler
This is needed to make L work correctly, and bionic tests pass

commit 00aaea364501b3b0abe58dae461136159df1e356 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.

c8cf3513ec 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.
