This patch adds an optional alias list to SYSCALLS.TXT. It is used to
create aliases for a syscall. For x86-64, lseek64 is an alias for lseek.

Although 'register' is deprecated, we need to use v1, and there's
no way to do that through register constraints on the assembler
fragment itself.

In c++11, register has been deprecated, and
libc is now built as gnu++11
From the documentation:
A register specifier is a hint to the implementation
that the variable so declared will be heavily used.
[ Note: The hint can be ignored and in most implementations
it will be ignored if the address of the variable is taken.
This use is deprecated (see D.2)

From the release notes:
Changes affecting current and near-future time stamps
Morocco now observes DST from the last Sunday in March to the last
Sunday in October, not April to September respectively. (Thanks
to Steffen Thorsen.)

This is basically the other half of I5de76f6c46ac87779f207d568a86bb453e2414de
from Pavel Chupin <pavel.v.chupin@intel.com>, but taking the exact upstream
_types.h instead of the modified version. (I was confused when I suggested
otherwise.)
I've also cleaned up the internal_types.h situation; we weren't gaining
anything from these empty files, and there is no upstream internal_types.h
for x86_64.

setjump/sigsetjmp and H.J. Lu's suggested changes to __rt_sigreturn.

FORTIFY_SOURCE prevents buffer overflows from occurring.
However, the error message often implies that we only
detect it, not prevent it.
Bring more clarity to the error messages by emphasizing
prevention over detection.

Got it all wrong on first patch. Somehow that didn't affect system
build, neither arm nor x86... something to think about.

The NDK ABI requires that you support SSE2, and the build system won't let you
build with ARCH_X86_HAVE_SSE2 set to false. So let's stop pretending this
constant is actually a variable, and let's remove the corresponding dead code.
Also, the USE_SSE2 and USE_SSE3 macros are unused, so let's not bother
setting them.

Make sure the buffer we're dealing with has enough room.
Might as well check for memory issues while we're here,
even though I don't imagine they'll happen in practice.

memcpy.a15.S/strcmp.a15.S files were submitted by ARM for use as the basis
for the memcpy/strcmp implementations in cortex-a15.
memset.S was moved in to the generic directory.
NOTE: memcpy.a9.S was submitted by Linaro to be the basis for the memcpy
for cortex-a9/cortex-a15 but has not been incorporated yet.

The check for __ARM_FEATURE_DSP being defined is pointless since it
is always defined.

malloc and family were not declared with __attribute__((alloc_size)).
This was (sometimes) preventing FORTIFY_SOURCE related functions
from knowing the size of the buffer it's dealing with, inhibiting
FORTIFY_SOURCE protections.
Add __attribute__((alloc_size))
Information about the alloc_size attribute can be found
at http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html

Clang and gcc default to different standards, so we should be explicit
about the versions we want to compile for.

I've no idea what _BITSIZE was supposed to be, glibc doesn't have it,
the BSDs don't have it, and no code is currently using it. But having
it set unconditionally to 32 sounds like a bad idea.

Clang (prior to 3.4) does not actually provide a declaration (or definition)
of _Unwind_GetIP() for ARM. We can work around this by writing our own
basic implementation using the available primitive operations.

Use basic .c versions of all functions for x86_64 until they are

This was causing conflicting declarations for the library definitions of
common functions like sprintf(), snprintf(), and strchr().

This is used to set/get TLS on x86_64. There's no public declaration
of this because it's not meant to be used outside the C library, like
glibc (though we don't currently have any visibility controls to ensure
this).
