d51a0b0f9d Base bcopy on memmove rather than memcpy.
POSIX defined bcopy to handle overlapping memory akin to memmove and
bionic appears to have always done so.

bb46afd6c4 Revert "Revert "Remove __sinit and __sdidinit.""
This reverts commit c8bae05f3f.

We were breaking init (ueventd) because we initialize system properties
before we initialize stdio. The new system property implementation uses
stdio to read from /property_contexts, so we end up touching stdio data
structures before they've been initialized.

This second attempt takes things further by removing the stdio initialization
function altogether. The data structures for stdin/stdout/stderr can be
statically initialized as data, and -- since we already had to give the
atexit implementation a backdoor for stdio -- we can just admit that we
need to clean up stdio, and that we always do so last.

This patch also removes the 17 statically pre-allocated file structures,
so the first fopen will now allocate a block of 10 (the usual overflow
behavior). I did this just to make my life simpler, but it's not actually
necessary to remove it if we want it back.

This reverts commit 4371961e00.

This broke booting; ueventd crashes with a null pointer dereference
somewhere in __sfp (but the kernel doesn't unwind, so I don't know
what was calling __sfp).

d7c7daada2 Remove the legacy endusershell/getusershell/setusershell stubs.
These don't work, aren't thread-safe, aren't in POSIX (or our header
files), and are only used by one app (whose developers I've contacted).
But the presence of these symbols causes configure to be confused, which
is a pain for Brillo.

891dedb935 libc: Fix 'index' symbol export.
The C library didn't export the 'index' symbol, but its C++ name-mangling
instead, which broke the ABI and prevented some applications from loading
properly.

The main reason was that the implementation under bionic/index.cpp relied
on the declaration to specify that the function has C linkage.

However, the declaration for index() was removed from both <string.h>
and <strings.h> in a recent patch, which made the compiler think it was
ok to compile the function with C++ linkage instead!

This patch does the following:

- Move index() definition to bionic/ndk_cruft.cpp and ensure it uses
  C linkage.

  Note that this removes index() from the 64-bit library entirely, this
  is intentional and will break source compatibility. Simply replacing
  an index() call with the equivalent strchr() should be enough to fix
  this in third-party code.

- Remove bionic/index.cpp from the tree and build files.

- Remove x86 assembly implementation from arch-x86/ to avoid conflict
  with the one in ndk_cruft.cpp

b30aff405a Revert "Revert "Lose the hand-written futex assembler.""
The problem with the original patch was that using syscall(3) means that
errno can be set, but pthread_create(3) was abusing the TLS errno slot as
a pthread_mutex_t for the thread startup handshake.

There was also a mistake in the check for syscall failures --- it should
have checked against -1 instead of 0 (not just because that's the default
idiom, but also here because futex(2) can legitimately return values > 0).

This patch stops abusing the TLS errno slot and adds a pthread_mutex_t to
pthread_internal_t instead. (Note that for LP64 sizeof(pthread_mutex_t) >
sizeof(uintptr_t), so we could potentially clobber other TLS slots too.)

I've also rewritten the LP32 compatibility stubs to directly reuse the
code from the .h file.

This reverts commit 75c55ff84e.
