* commit '1658691e0cfe2eb221bee837649de1907a579a0b':
  <pthread.h> fixes and pthread cleanup.

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.

Experiment shows that the claim in the makefile was false: gdb works fine
setting breakpoints in these functions when compiled without special treatment.

I really don't want to add yet another copy for aarch64.

Also sort arm, mips, and x86.

Also silence the "TARGET_ARCH_VARIANT" warning for non-ARM; Intel and MIPS
have both complained about it.

2b6e43e00e Explain the sigprocmask in pthread_exit.
Also remove the SIGSEGV special case, which was probably because
hand-written __exit_with_stack_teardown stubs used to try to cause
SIGSEGV if the exit system call returned (which it never does, so
that dead code disappeared).

Also move the sigprocmask into the only case where it's necessary ---
the one where we unmap the stack that would be used by a signal
handler.

feaa89a1bc AArch64: Add support for AArch64 to the syscall interface
This patch adds support for AArch64 to the syscall interface. The kernel
implementation exports a set of canonical syscalls, therefore some of
the userspace exported syscalls are implemented as stubs based on the
canonical set.

From the release notes:

  Changes affecting current and future time stamps:

    Libya has switched its time zone back to UTC+2 without DST,
    instead of UTC+1 with DST.  (Thanks to Even Scharning.)

    Western Sahara (Africa/El_Aaiun) uses Morocco's DST rules.
    (Thanks to Gwillim Law.)

  Changes affecting future time stamps:

    Acre and (we guess) western Amazonas will switch from UTC-4 to UTC-5
    on 2013-11-10.  This affects America/Rio_Branco and America/Eirunepe.
    (Thanks to Steffen Thorsen.)

    Add entries for DST transitions in Morocco in the year 2038.
    This avoids some year-2038 glitches introduced in 2013g.
    (Thanks to Yoshito Umaoka for reporting the problem.)

6b53c2349a Fix the exit syscall stub's name.
I've left the exit_group syscall as _exit because otherwise we'd have to
convince the compiler that our _exit (which just calls __exit_group) is
actually "noreturn", and it seems like that would be less clean than just
cutting out the middleman.

We'll just have to trust ourselves not to add anything to SYSCALLS.TXT
that ought to be private but that only has a single leading underscore.
Hopefully we can manage that.
