9ad2a73ed6 Fix assembler errors in generic arm strlen.c. 
Tested using a static version of the strlen libc_test program
on a nexus7 that uses the generic code.

Merge from internal master.

0aa9b52efa Add new optimized strlen for arm. 
This optimized version is primarily targeted at cortex-a15.

Tested on all nexus devices using the system/extras/libc_test strlen test.
Tested alignments from 1 to 32 that are powers of 2.
Tested that strlen does not cross page boundaries at all alignments.

Speed improvements listed below:

cortex-a15
- Sizes >= 32 bytes, ~75% improvement.
- Sizes >= 1024 bytes, ~250% improvement.

cortex-a9
- Sizes >= 32 bytes, ~75% improvement.
- Sizes >= 1024 bytes, ~85% improvement.

krait
- Sizes >= 32 bytes, ~95% improvement.
- Sizes >= 1024 bytes, ~160% improvement.

Merge from internal master.

aa754dca90 Improve stack overflow diagnostics. 
We notify debuggerd of problems by installing signal handlers. That's
fine except for when the signal is caused by us running off the end of
a thread's stack and into the guard page.

any more.

da4a3e6515 EABI syscall cleanup. 
We cleaned up the auto-generated ones a while back to not touch
the stack unnecessarily if they have <= 4 arguments. This patch
cleans up some hand-crafted ones.

Also improve comments in clone.S.

b95cf0d23a Fix pthread_getattr_np, pthread_attr_setguardsize, and pthread_attr_setstacksize. 
pthread_getattr_np was reporting the values supplied to us, not the values we
actually used, which is kinda the whole point of pthread_getattr_np.

pthread_attr_setguardsize and pthread_attr_setstacksize were reporting EINVAL
for any size that wasn't a multiple of the system page size. This is
unnecessary. We can just round like POSIX suggests and glibc already does.

Also improve the error reporting for pthread_create failures.

ce4783ce76 Upgrade to tzcode2013d. 
Well, kinda... localtime.c still contains a bunch of Android-specific
hacks, as does strftime.c. But the other files are now exactly the same
as upstream.

This catches up with several years of bug fixes, and fixes most of the
compiler warnings that were in this code. (Just two remain.)

glibc doesn't have these, and they prevent ping from building out of
the box because it assumes it can define them.
