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.

ARM Cortex A8 use 64 bytes and ARM Cortex A9 use 32 bytes cache line
size.
The following patch:
Adds code to adjust memcpy cache line size to match A9 cache line
size.
Adds a flag to select between 32 bytes and 64 bytes cache line
size.
Copyright (C) ST-Ericsson SA 2010
Modified neon implementation to fit Cortex A9 cache line size

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).

libc: continue to use Android's custom linker script

By default, Android no longer compiles code using it's custom
linker script /build/core/armelf.xsc. However, this causes
problems for libc. Certain programs linked using older versions
of GOLD expect libc.so to export __exidx_start and __exidx_end.
Removing the custom linker script causes libc.so not to export
those symbols.
For now, continue using the old linker script, until we can
figure out a better solution.

Since e19d702b8e33, dlsym and friends use recursive mutexes that
require the current thread id, which is not available before the libc
constructor. This prevents us from using dlsym() in .preinit_array.
This change moves TLS initialization from libc constructor to the earliest
possible point - immediately after linker itself is relocated. As a result,
pthread_internal_t for the initial thread is available from the start.
As a bonus, values stored in TLS in .preinit_array are not lost when libc is
initialized.

This change fixes a segmentation fault in the libc unwinder when it goes
past __libc_init.
Unwind instructions for __libc_init direct it to grab the return address from
the stack frame. Without this change, the unwinder gets a wild address and
looks up further unwind instructions for the routine at that address. If it's
unlucky enough to hit an existing function, it will try to unwind it. Bad
things happen then.
With this change, the return address always points to the _start function,
which does not have unwind instructions associated with it. This stop the
unwind process.
__libc_init never returns, so this does not affect program execution, other
than adding 4 bytes on the main thread stack.

The END macro was put too far down which made the linker complain about
it. Move up to the end of the code.

Marking segments read-only was pushing the alignment of __on_dlclose by
2 bytes making it unaligned. This change makes sure the ARM code is
aligned to the 4 byte boundary.

From the release notes:
africa
Summer time changes for Morocco (to start late April 2012)
asia
Changes for 2012 for Gaza & the West Bank (Hebron) and Syria
northamerica
Haiti following US/Canada rules for 2012 (and we're assuming,
for now anyway, for the future).
Also include a change made internally to the 'generate' script as part of
the tzdata2011m update that apparently never made it to AOSP; the original
checkin comment for which was:
Update to tzdata2011m.
Fixes for Europe/Tiraspol (Moldova) and all four Ukrainian zones.
Also show the MD5 of the downloaded data, for comparison against the MD5
given in the announcement mails. (There's a plan to move to proper signing,
but that's not implemented on their end yet.)
(I'm repeating the tzdata change for the convenience of anyone grepping the
log, since the 2012 tzdata releases also contain the 2011m changes; 2011m
is the only missing release I noticed.)

Currently Renderscript sample code RsBalls crashed on x86 when SSE2
enabled. The root cause is that the stack was not 16-byte aligned
from the beginning when the processes/threads were created, so the
RsBalls crashed when SSE2 instructions tried to access the variables
on the stack.
- For the thread created by fork():
Its stack alignment is determined by crtbegin_{dynamic, static}.S
- For the thread created by pthread_create():
Its stack alignment is determined by clone.S. __thread_entry( ) is
a standard C function. In order to have its stack be aligned with
16 byte properly, __thread_entry() needs the stack with following
layout when it is called:
layout #1 (correct)
--------------
| |
-------------- <--ESP (ECX - 20)
| ret EIP |
-------------- <--ECX - 16
| arg0 |
-------------- <--ECX - 12
| arg1 |
-------------- <--ECX - 8
| arg2 |
-------------- <--ECX - 4
| unused |
-------------- <--ECX (16-byte boundary)
But it has following layout for now:
layout #2: (incorrect)
--------------
| |
-------------- <--ESP (ECX - 16)
| unused |
-------------- <--ECX - 12
| arg0 |
-------------- <--ECX - 8
| arg1 |
-------------- <--ECX - 4
| arg2 |
-------------- <--ECX (16-byte boundary)
Fixed in this patch.

Root cause:
The atfork uses the mutex handler_mutex to protect the atfork_head. The
parent will call __bionic_atfork_run_prepare() to lock the handler_mutex,
and need both the parent and child to unlock their own copy of handler_mutex
after fork. At that time, the owner of hanlder_mutex is set as the parent.
If we apply the kernel_id fix, then the child's kernel_id will be set as
child's tid.
The handler_mutex is a recursive lock, and pthread_mutex_unlock(&hander_mutex)
will fail because the mutex owner is the parent, while the current tid
(__get_thread()->kernel_id) is child, not matched with the mutex owner.
At that time, the handler_mutex is left in lock state.If the child wants to
fork other process after than, then it will try to lock handler_mutex, and
then be deadlocked.
Fix:
Since the child has its own copy of vm space from the the parent, the
child space's handler_mutex should be reset to the initialized state.
