libc: add getauxval()
Add support for getauxval(). This method allows a program an easy way
to retrieve information from the kernel auxiliary vector, and will
hopefully replace other clumsy ways of accessing this same information.
This particular function was also added to glibc in glibc 2.16.

- add signalfd4 system call (function name and syscall

libc/tools/gensyscalls.py. This patch is adding
the generated files since the build system
does not call gensyscalls.py.

Spotted while running the tests on MIPS, where sigset_t is
actually large enough. The bits in sigset_t are used such that
signal 1 is represented by bit 0, so the range of signals is
actually [1, 8*sizeof(sigset_t)]; it seems clearer to reword
the code in terms of valid bit offsets [0, 8*sizeof(sigset_t)),
which leads to the usual bounds checking idiom.

You could argue that this is hurting people smart enough to have manually

implement their own sigset functions too.
I wonder whether our least unpleasant way out of our self-inflicted 32-bit
cesspool is to have equivalents of _FILE_OFFSET_BITS such as _SIGSET_T_BITS,
so calling code could opt in? You'd have to be careful passing sigset_t
arguments between code compiled with different options.

Support GNU_RELRO for static executables.
In
9ec0f03a0d0b17bbb94ac0b9fef6add28a133c3a, we added dynamic
linker support for GNU_RELRO protections. These protections
make certain regions of memory read-only, helping protect certain
data structures from accidental or deliberate modifications.
This change adds GNU_RELRO support to STATIC executables. We can
determine if we're compiled with relro protections by examining
our own program headers, which is passed to us by the kernel
in the AT_PHDR and AT_PHNUM auxiliary vectors.
Parts of this code were stolen from the dynamic linker.

Add optimized version of memcpy for Cortex A9
Adds new code to memcpy function, optimized for Cortex A9.
Adds new ARM-only loop, for operations where source and
destination are aligned.
Copyright (C) ST-Ericsson SA 2010
Modified neon implementation to fit Cortex A9 cache line size,
for those running 32 bytes L2 cache line size.
Also split the implementation in aligned and unaligned access,
for those that allows unaligned memory access with Neon.
For totally aligned operations, arm-only code is used.
