libc/arch-arm/bionic/memcpy.a9.S: memcpy from cortex-strings.

This memcpy code uses NEON/VFP to achieve very good performance
on ARMv7-A processors. It is specifically tuned for A15 but should
provide good performance on A9 also. It is equivalent to the code
in cortex-strings rev 116.

This patch is a follow up the existing gerrit change:

I7f6f77995f3ca903ad9c66d14261441667a2a935

This version includes a tweak for performance on misaligned
buffers and splits the header comment into license and
documentation sections.

Make bionic's <netinet/icmp6.h> standalone, like glibc's.

This removes the need for a bionic-specific hack in external/iproute2.

Remove <netinet/icmp6.h> ni_* macros.

glibc doesn't have these, and they prevent ping from building out of
the box because it assumes it can define them.

[MIPS] Rewrite MIPS crtbegin* as C files.

This updates the MIPS arch to be much more in
sync with the commit Nick Kralevich made last
June; see 9d40326830c2bd407427889c554adeb915ee6b4a.

    Rewrite
     crtbegin.S        -> crtbegin.c
     crtbegin_so.S     -> crtbegin_so.c
     __dso_handle.S    -> __dso_handle.c
     __dso_handle_so.S -> __dso_handle_so.c
     atexit.S          -> atexit.c

Previously __do_global_dtors_aux was in the tasks
__FINI_ARRAY__ linked with crtbegin.S and it now being
removed as there is no need to call a destructor just
before terminating a process.

Shared libraries, on the other hand, are linked with
crtbegin_so.c and have a hidden destructor declared
to allow the bionic linker to call __on_dlclose().

Remove some non-unused makefile generality.

MIPS uses .c files like ARM and x86 now.

Avoid sign extension of the mmap offset.
off_t is signed to support seeking backwards, but that's a liability
when using off_t to represent a subset of a file.

Tell the dns resolver about our domains.

A refactor caused us to not tell the resolver about search domains

fix broken pointer overflow check ns_name_unpack()

Many compilers optimize away the overflow check `msg + l < msg',
where `msg' is a pointer and `l' is an integer, because pointer
overflow is undefined behavior in C.

Use a safe precondition test `l >= eol - msg' instead.

syslog needs a valid socket path for _PATH_LOG

/dev/kmsg is a character device already used for different purposes.
Most distribution use /dev/log for _PATH_LOG but this path is already used
by logcat.
I suggest using /dev/syslog.
This change was tested with busybox's syslogd.
