6a51defa03 Fix __get_tls() in static C library to use kernel helpers.
This is needed to fix gdbserver's handling of threaded programs,
among other things.

50ace4fec5 Remove compiler warnings when building Bionic.
Also add missing declarations to misc. functions.
Fix clearerr() implementation (previous was broken).
Handle feature test macros like _POSIX_C_SOURCE properly.

6a9b888d7c Allow static C++ destructors to be properly called on dlclose().
With this patch, _and_ an upcoming build/ patch, the destruction
of static C++ objects contained in shared libraries will happen
properly when dlclose() is called.

Note that this change introduces crtbegin_so.S and crtend_so.S which
are currently ignored by the build system.

+ move definition of __dso_handle to the right place
  (before that, all shared libraries used the __dso_handle
   global variable from the C library).

  Note that we keep a 'weak' __dso_handle in aeabi.c to avoid
  breaking the build until the next patch to build/core/combo/
  appears. We will be able to remove that later.

+ move bionic/aeabi.c to arch-arm/bionic/ (its proper location)

Change-Id: Ie771aa204e3acbdf02fd30ebd4150373a1398f39
NOTE: The NDK will need to be modified to enable this feature in
      the shared libraries that are generated through it.

e4fa46e75c Set SA_RESTORER in sigaction()
GDB looks for specific opcode sequences when trying to recognize a stack
frame as a signal trampoline.  The sequences it looks for happen to be those
created when SA_RESTORER is set, since glibc always sets a restorer.  This
patch does the same here, so that the trampolines can be correctly identified.

before changing users. This is so we can properly account for cpu time
per uid.

97cf7f3394 Implement clone() C library function properly.
Only provide an implementation for ARM at the moment, since
it requires specific assembly fragments (the standard syscall
stubs cannot be used because the child returns in a different
stack).

Turns out we don't need it afterall (needed a stable sort anyways).
So, we'll make that change in the dev branch instead.

754c178ae5 Add qsort_r() implementation to the C library.
NOTE: This replaces qsort.c with the FreeBSD version. While
      the patch changes the source, it should not alter the
      implementation that should use the exact same algorithm.

b74ceb25aa Split libc_debug.so into two .so modules loaded on demand from libc.so
This change is intended to eliminate need to replace libc.so with libc_debug.so in order to enablememory allocation debugging.
This is also the first step towards implementing extended memoryallocation debugging using emulator's capabilities in monitoring memory access.

4a05d12cf5 Fix TLS access for ARMv6 and beyond.
For performance reasons, we don't call the kernel helper. Instead, we directly
access the TLS register on ARMv6 and higher. For ARMv5TE, keep using the hard-coded
address populated by the kernel on each task switch.

NOTE: Since we don't call the kernel helper, this must precisely match your
      kernel configuration. This is controlled by setting the ARCH_ARM_HAVE_TLS_REGISTER
      variable to 'true' in your board configuration file.
