Elliott Hughes
e7dccdf683 Clear the return address register in __bionic_clone.
The unwinder will end up on the parent thread's stack if the return
address register is not cleared.

a7821b7121 Use __typeof__() instead of typeof()
typeof() is a gcc builtin and is not always available (such as clang when
-std=c*). Both gcc and clang always expose __typeof__(), so just use that.

aa50585d96 Restore __srefill for LP32.
The NDK apparently includes an android_support.a library that
refers to __srefill in its copy of the vsnprintf implementation.

35d90bb6ec Restore __srget and __swbuf for LP32.
Anthony King <anthonydking@slimroms.net> reports that for Grouper the
Nvidia GL blobs need access to __swbuf. This is because the old <stdio.h>
had inline getc and putc implementations that directly referred to these
symbols.

libmono from Unity still requires tkill(2).

fd0ce866ce Revert "Add optimized AArch64 versions of bcopy and wmemmove based on memmove"
This reverts commit 8167dd7cb9.

For some reason I thought the bcopy change was bzero. The bcopy code doesn't pass our tests, so reverting until I can figure out what's wrong.

8df0fe0c74 Clear link register in __bionic_clone.
Since __bionic_clone uses tail-call to invoke __bionic_clone_entry,
at runtime the unwinder will reach the stack of the clone() function,
which belongs to the parent thread, if the link register is not cleared.

2899de9b05 Hide various stdio implementation details.
I've left __sF exposed since that's how the OpenBSD stdin, stdout, stderr
are implemented. Other BSDs and glibc use a separate global for each instead
of an array.

92687e41bc Cleaned up pthread rwlocks implementation.
- used underscore_style_for_vars
- extracted time related functionality into a function
- cleaned up style
- removed unused fields from pthread_rwlock_t on LP64
- changed reservation in pthread_rwlock_t so that the size of the
structure equals glibc version

6e599a904b Remove the tkill(2) stub.
glibc doesn't have tkill or tgkill and says "use syscall(3) instead".
I've left tgkill since it's quite widely used, but there's no reason
to have tkill as well.

d5ed63a6a8 Hide most of the private futex functions.
Also hide part of the system properties compatibility code, since
we needed to touch that to keep it building.

I'll remove __futex_syscall4 and futex in a later patch.
