* commit '800ad824':
  Provide glibc-compatible SYS_* aliases for the __NR_* constants.

This helps us remove another external/strace bionic hack.

* commit '6eb978c9':
  Expose wait4 as wait4 rather than __wait4.

This helps strace(1) compile with one fewer hack.

* commit '86c31849':
  Create arch specific versions of strcmp.

This uses the new strcmp.a15.S code as the basis for new versions
of strcmp.S.

The cortex-a15 code is the performance optimized version of strcmp.a15.S
taken with only the addition of a few pld instructions.
The cortex-a9 code is the same as the cortex-a15 code except that the
unaligned strcmp code was taken from the original strcmp.S.
The krait code is the same as the cortex-a15 code except that one path
in the unaligned strcmp code was taken from the original strcmp.S code
(the 2 byte overlap case).
The generic code is the original unmodified strmp.S from the bionic
subdirectory.

All three new versions underwent these test cases:

Strings the same, all same size:
- Both pointers double word aligned.
- One pointer double word aligned, one pointer word aligned.
- Both pointers word aligned.
- One pointer double word aligned, one pointer 1 off a word alignment.
- One pointer double word aligned, one pointer 2 off a word alignment.
- One pointer double word aligned, one pointer 3 off a word alignment.
- One pointer word aligned, one pointer 1 off a word alignment.
- One pointer word aligned, one pointer 2 off a word alignment.
- One pointer word aligned, one pointer 3 off a word alignment.
For all cases where it made sense, the two pointers were also tested
swapped.

Different strings, all same size:
- Single difference at double word boundary.
- Single difference at word boudary.
- Single difference at 1 off a word alignment.
- Single difference at 2 off a word alignment.
- Single difference at 3 off a word alignment.

Different sized strings, strings the same until the end:
- Shorter string ends on a double word boundary.
- Shorter string ends on word boundary.
- Shorter string ends at 1 off a word boundary.
- Shorter string ends at 2 off a word boundary.
- Shorter string ends at 3 off a word boundary.

For all different cases, run them through the same pointer alignment
cases when the strings are the same size.
For all cases the two pointers were also tested swapped.

  Hide various symbols that shouldn't be exposed.

* commit 'c1416647':
  Clean up internal libc logging.

A mangled symbol in libc.so is a symbol that shouldn't be exported
by libc.so.

We only need one logging API, and I prefer the one that does no
allocation and is thus safe to use in any context.

Also use O_CLOEXEC when opening the /dev/log files.

Move everything logging-related into one header file.

* commit 'd30b9f09':
  Remove unused arm defines.

The defines HAVE_32_BYTE_CACHE_LINES and ARCH_ARM_USE_NON_NEON_MEMCPY
are not used by any code. The previous memcpy code that used these
has been split into different architecture versions to avoid the need
for them.

* commit 'f861bc5c':
  Don't search off the end of the index for bad Olson ids.

In the old code, the index was a file to itself, so it made sense to
read until you hit the end of the file. In the new code, the index is
followed by hundreds of KiB of data, so we need to just search the
index.
