[MIPS] Fix the warning originating from the kernel header signal.h
Add the posix_memalign(3) function to bionic

The posix_memalign(3) function is very similar to the traditional
memalign(3) function, but with better error reporting and a guarantee
that the memory it allocates can be freed.  In bionic, memalign(3)
allocated memory can be freed, so posix_memalign(3) is just a wrapper
around memalign(3).

Remove expired dns cache entries before removing oldest

A suggestion how to make a smarter delete function when the cache
is full. First look through the entire cache and remove all entries
which have expired. If none use the old solution and just remove
the last entry in the MRU list.

bionic: fix integer overflows in chk_malloc(), leak_malloc(), and leak_memalign()

The allocation size in chk_malloc(), leak_malloc(), and leak_memalign()
functions may be rounded up to a small value, leading to buffer overflows.
The code only runs in debugging mode.

This patch complements commit 6f04a0f4 (CVE-2009-0607).

Adjust memcpy for ARM Cortex A9 cache line size
Let pthread_create fail if schedparam can't be set

The creation of a thread succeeds even if the requested scheduling
parameters can not be set. This is not POSIX compliant, and even
worse, it leads to a wrong behavior. Let pthread_create() fail in this
case.

Implement the "abort" stub in assembly for ARM.

So that we can always get the full stack trace regardless of gcc's handling
of the "noreturn" attribute associated with abort().

pthread: Invalidate stale stack pointers on pthread_exit()

A call to pthread_key_delete() after pthread_exit() have unmapped the stack of a thread
but before the ongoing pthread_join() have finished executing will result in an access
to unmapped memory.
Avoid this by invalidating the stack_base and tls pointers during pthread_exit().

This is based on the investigation and proprosed solution by

bionic: allow the board to customize MALLOC_ALIGNMENT

Currently the dlmalloc allocates the memory with 8-byte alignment.
According to the com.aurorasoftworks.quadrant.ui.professional benchmark data:
We can get much better memory performance if we change it to be 16-byte aligned.
For example, On Nexus-S:
8-byte aligned :
    1378 1070  1142 1665 1765  1163 1179  1263  1404 avg: 1336.555555556
16-byte aligned:
    1691 1731  1780 1691 1671  1678 1802  1758  1780 avg: 1731.333333333
                                                    gain: 29.53%

That patch provides flexibity to customize the MALLOC_ALIGNMENT from the
board config.The macro MALLOC_ALIGNMENT defaults to 8.
To change it, please define BOARD_MALLOC_ALIGNMENT in the BoardConfig.mk:
BOARD_MALLOC_ALIGNMENT := <whatever>
