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).

libc/x86: ensure the stack 16-byte aligned when tasks created

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 - 8
| arg2       |
-------------- <--ECX - 4

But it has following layout for now:
layout #2: (incorrect)

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.

bionic: Fix wrong kernel_id in pthread descriptor after fork()

After forking, the kernel_id field in the phtread_internal_t returned by pthread_self()
is incorrect --- it's the tid from the parent, not the new tid of the
child.

The root cause is that: currently the kernel_id is set by
_init_thread(), which is called in 2 cases:
(1) called by __libc_init_common(). That happens when the execv( ) is
called after fork( ). But when the zygote tries to fork the android
application, the child application doesn't call execv( ), instread, it
tries to call the Java main method directly.
(2) called by pthread_create(). That happens when a new thread is
created.

For the lead thread which is the thread created by fork(), it should
call execv() but it doesn't, as described in (1) above. So its kernel_id
will inherit the parent's kernel_id.

Fixed it in this patch.

David 'Digit' Turner [Mon, 23 Jan 2012 14:15:30 +0000 (15:15 +0100)]
libc: Define new symbol visibility macros

This patch defines a few new macros that can be used to control the
visibility of symbols exported by the C library:

- ENTRY_PRIVATE() can be used in assembly sources to indicate
  that an assembler function should have "hidden" visibility, i.e.
  will never be exported by the C library's shared library.

  This is the equivalent of using __LIBC_HIDDEN__ for a C function,
  but ENTRY_PRIVATE() works like ENTRY(), and must be used with
  END() to tag the end of the function.

- __LIBC_ABI_PUBLIC__ can be used to tag a C functions as being
  part of the C library's public ABI. This is important for a
  few functions that must be exposed by the NDK to maintain
  binary compatibility.

  Once a symbol has been tagged with this macro, it shall
  *never* be removed from the library, even if it becomes
  directly unused due to implementation changes
  (e.g. __is_threaded).

- __LIBC_ABI_PRIVATE__ can be used for C functions that should
  always be exported by the C library because they are used by
  other libraries in the platform, but should not be exposed
  by the NDK. It is possible to remove such symbols from the
  implementation if all callers are also modified.

+ Add missing END() assembly macro for x86

Update to tzdata2011n.

There are three changes of note - most urgently, Cuba (America/Havana)
has extended summer time by two weeks, now to end on Nov 13, rather than
the (already past) Oct 30.   Second, the Pridnestrovian Moldavian Republic
(Europe/Tiraspol) decided not to split from the rest of Moldova after
all, and consequently that zone has been removed (again) and reinstated
in the "backward" file as a link to Europe/Chisinau.   And third, the
end date for Fiji's summer time this summer was moved forward from the
earlier planned Feb 26, to Jan 22.

Apart from that, Moldova (MD) returns to a single entry in zone.tab
(and the incorrect syntax that was in the 2011m version of that file
is so fixed - it would have been fixed in a different way had this
change not happened - that's the "missing" sccs version id).

readdir: fix interface to kernel getdents64 function

Issue:
  The kernel will pad the entry->d_reclen in a getdents64 call to a
  long-word boundary.  For very long records, this could exceed the
  size of a struct dirent. The mismatch in the size was causing error
  paranoid checking code in bionic to fail... thus causing an early
