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.

This patch adds support for AArch64 to strtod.c definitions.

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.)

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.

arch/mips/kernel/syscall.c has a special sysm_pipe wrapper, but there's
no special treatment of pipe2 because it carries no historical baggage.

(aarch64 kernels only have the newer system calls.)
Also expose the new functionality that's exposed by glibc in our header files.

Modern architectures only get the *at(2) system calls. For example,
aarch64 doesn't have open(2), and expects userspace to use openat(2)
instead.

This patches fixes the definitions for STDINT_LIMITS on __LP64__

We need to pull the arguments off the child stack and put them into the
registers they're expected to be in.

SOCK_CLOEXEC is used to atomically set close-on-exec flag for the new
descriptor(s), and SOCK_NONBLOCK is used to mark descriptor(s) as
non-blocking.

Also clean up <signal.h> and revert the hacks that were necessary
for 64-bit in linker/debugger.cpp until now.

The processed uapi directory is now placed at libc/kernel/uapi as
opposed to libc/kernel/common/uapi as it contains
architectural-dependent headers now.

This cruft dates from a time when bionic would only output syscall
contants for the syscalls mentioned in SYSCALLS.TXT. I fixed that
a long time ago, but never followed through with the removal of what
was then confusingly called "stub" and was recently renamed "custom".
