ea29cd5a4a Eliminate duplicate copies of constants.
sys/personality.h and linux/personality.h contain mostly
identical contents. Eliminate dups.

linux-unistd.h was here for reference purposes, but shouldn't
have been accessible to client code. Delete it.

87043f9c89 res_send: Avoid spurious close()s and (rare) failure
When looping over the current list of sockets we are connected to,
use getpeername() not getsockname() to find out who the remote
end is.  This change avoids spurious close() and (rare) failure.

Origin: ISC bug #18625 and fixed in libbind 6.0

28a7c35fea execvp: bcopy() is deprecated. Use memcpy() instead
The function bcopy() is marked as LEGACY in POSIX.1-2001 and removed in
POSIX.1-2008. memcpy (POSIX.1-2001) is its recommended replacement.

208898ee77 libc: remove private declarations from <time.h> and <resolv.h>
This patch is used to remove private C library declarations from the
public headers (that are exported to the NDK). It should *only* be
submitted after all other patches modifying the users of said
private functions have been submitted to the tree, to avoid
breakages.

11f3d5a431 libc: Copy private C library declarations to private/
This patch is the first in a series that aims at cleaning up the
public C library headers (which end up being distributed with the NDK).

<resolv.h> and <time.h> contain declarations that should not be public.
They are used by other parts of the platform, but NDK applications should
not use or rely on them.

So copy them to private <bionic_time.h> and <resolv_iface.h> headers
and use a guard macro to avoid conflicts when both headers are included
at the same time.

The idea is that we're going to fix the other platform modules to
include these private headers. After this is done, we will remove the
duplicate definitions from <resolv.h> and <time.h>

ecd0e95a02 Adding a timeout to tcp dns lookup connects.
TCP isn't supported on some dns servers, which makes the old code
hang forever.

NOT adding a stopship to remove debugging stuff - it was too painful
(14s timeout on failed tcp dns lookups) so we decided not to bother people.

This change makes linker handling of .preinit_array compliant with the
System V ABI:

"These [pre-initialization] functions are executed after the dynamic linker has
built the process image and performed relocations but before any shared object
initialization functions."

a37f372973 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
  "end" when reading the dirent structures from the kernel buffer.

Test:
 ls
 mkdir abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstu
 ls

85aad90956 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).

a5cb76bca0 libc: x86: Use SSE2 or SSSE3 optimized routines when possible.
This patch uses the new hardware feature macros for x86 to define
various compile-time macros used to make the C library use
SSE2 and/or SSSE3 optimized memory functions for target CPUs
that support these features.

Note that previously, we relied on the macros being defined by
build/core/combo/TARGET_linux-x86.mk, but this is no longer the
case.

7c0c379372 implement pthread mutex deadlock detection
this works by building a directed graph of acquired
pthread mutexes and making sure there are no loops in
that graph.

this feature is enabled with:

    setprop debug.libc.pthread 1

when a potential deadlock is detected, a large warning is
output to the log with appropriate back traces.

currently disabled at compile-time. set PTHREAD_DEBUG_ENABLED=1
to enable.

022d303116 libc: optimize pthread mutex lock/unlock operations (1/2)
This patch provides several small optimizations to the
implementation of mutex locking and unlocking. Note that
a following patch will get rid of the global recursion
lock, and provide a few more aggressive changes, I
though it'd be simpler to split this change in two parts.

+ New behaviour: pthread_mutex_lock et al now detect
  recursive mutex overflows and will return EAGAIN in
  this case, as suggested by POSIX. Before, the counter
  would just wrap to 0.

- Remove un-necessary reloads of the mutex value from memory
  by storing it in a local variable (mvalue)

- Remove un-necessary reload of the mutex value by passing
  the 'shared' local variable to _normal_lock / _normal_unlock

- Remove un-necessary reload of the mutex value by using a
  new macro (MUTEX_VALUE_OWNER()) to compare the thread id
  for recursive/errorcheck mutexes

- Use a common inlined function to increment the counter
  of a recursive mutex. Also do not use the global
  recursion lock in this case to speed it up.

6c6de44f04 libc: optimize pthread_once() implementation.
This patch changes the implementation of pthread_once()
to avoid the use of a single global recursive mutex. This
should also slightly speed up the non-common case where
we have to call the init function, or wait for another
thread to finish the call.
