f0870c3bfe Fix some pthread symbols build as C++ symbol under x64 lunch.
Functions protected with !defined(__LP64__) will be get build as C++
symbols for X64 build. This is not the desired work. So protect the
implementation with !defined(__LP64__) as well.

c3f114037d <pthread.h> fixes and pthread cleanup.
<pthread.h> was missing nonnull attributes, noreturn on pthread_exit,
and had incorrect cv qualifiers for several standard functions.

I've also marked the non-standard stuff (where I count glibc rather
than POSIX as "standard") so we can revisit this cruft for LP64 and
try to ensure we're compatible with glibc.

I've also broken out the pthread_cond* functions into a new file.

I've made the remaining pthread files (plus ptrace) part of the bionic code
and fixed all the warnings.

I've added a few more smoke tests for chunks of untested pthread functionality.

We no longer need the libc_static_common_src_files hack for any of the
pthread implementation because we long since stripped out the rest of
the armv5 support, and this hack was just to ensure that __get_tls in libc.a
went via the kernel if necessary.

This patch also finishes the job of breaking up the pthread.c monolith, and
adds a handful of new tests.

84114c8dd5 Improve stack overflow diagnostics (take 2).
This reverts commits eb1b07469f2b5a392dc1bfd8adc211aea8c72bc5 and
d14dc3b87fbf80553f1cafa453816b7f11366627, and fixes the bug where
we were calling mmap (which might cause errno to be set) before
__set_tls (which is required to implement errno).

aa754dca90 Improve stack overflow diagnostics.
We notify debuggerd of problems by installing signal handlers. That's
fine except for when the signal is caused by us running off the end of
a thread's stack and into the guard page.

b95cf0d23a Fix pthread_getattr_np, pthread_attr_setguardsize, and pthread_attr_setstacksize.
pthread_getattr_np was reporting the values supplied to us, not the values we
actually used, which is kinda the whole point of pthread_getattr_np.

pthread_attr_setguardsize and pthread_attr_setstacksize were reporting EINVAL
for any size that wasn't a multiple of the system page size. This is
unnecessary. We can just round like POSIX suggests and glibc already does.

Also improve the error reporting for pthread_create failures.

3e898476c7 Revert "Revert "More pthreads cleanup.""
This reverts commit 6f94de3ca49e4ea147b1c59e5818fa175846518f

(Doesn't try to increase the number of TLS slots; that leads to
an inability to boot. Adds more tests.)

2a1bb4e646 More pthreads cleanup.
POSIX says pthread_create returns EAGAIN, not ENOMEM.

Also pull pthread_attr_t functions into their own file.

Also pull pthread_setname_np into its own file.

Also remove unnecessary #includes from pthread_key.cpp.

Also account for those pthread keys used internally by bionic,
so they don't count against the number of keys available to user
code. (They do with glibc, but glibc's limit is the much more
generous 1024.)

Also factor out the common errno-restoring idiom to reduce gotos.
