Found by adapting the simple unit tests for libc logging to test
snprintf too. Fix taken from upstream OpenBSD without updating
the rest of stdio.

The tests are using /data/data which is not accessible to a non-root
user. Change this to /data/local/tmp which is accessible to all users.

The properties tests creates a temporary directory in /data/nativetest,
but this directory might not exist in all circumstances.
Change this to create the temporary directory in /data/local/tmp.

I accidentally did a signed comparison of the size_t values passed in
for three of the _chk functions. Changing them to unsigned compares.
Add three new tests to verify this failure is fixed.

The backtrace when a fortify check failed was not correct. This change
adds all of the necessary directives to get a correct backtrace.
Fix the strcmp directives and change all labels to local labels.
Testing:
- Verify that the runtime can decode the stack for __memcpy_chk, __memset_chk,
__strcpy_chk, __strcat_chk fortify failures.
- Verify that gdb can decode the stack properly when hitting a fortify check.
- Verify that the runtime can decode the stack for a seg fault for all of the
_chk functions and for memcpy/memset.
- Verify that gdb can decode the stack for a seg fault for all of the _chk
functions and for memcpy/memset.
- Verify that the runtime can decode the stack for a seg fault for strcmp.
- Verify that gdb can decode the stack for a seg fault in strcmp.

The libcorkscrew stack unwinder does not understand cfi directives,
so add .save directives so that it can function properly.
Also add the directives in to strcmp.S and fix a missing set of
directives in cortex-a9/memcpy_base.S.

This adds mmap64() to bionic so that it is possible to have
large offset passed to kernel. However, the syscall mechanism
only passes 32-bit number to kernel. So effectively, the
largest offset that can be passed is about 43 bits (since
offset is signed, and the number passed to kernel is number
of pages (page size == 4K => 12 bits)).

__page_shift and __page_size were accidentally declared in unistd.h with
C linkage - their implementation needs to use the same linkage.
Going forward, though, let's stop the inlining madness and let's kill
the non-standard __getpageshift(). This patch takes getpagesize(3) out
of line and removes __getpageshift but fixes __page_shift and __page_size
for backwards binary compatibility.
