The current tests don't test the functionality of realloc in detail.
Add a new test for realloc that exercises some of the corner cases
that are not otherwise tested.

* malloc/Makefile: Add tst-realloc to tests.
* malloc/tst-realloc.c: New file.
The benchmark for memcpy got disabled accidentally. Re-enable it.

* benchtests/Makefile (string-bench): Add memcpy.
This change synchronizes the glibc headers with the Linux kernel
headers and arranges to coordinate the definition of structures
already defined the Linux kernel UAPI headers.
It is now safe to include glibc's netinet/in.h or Linux's linux/in6.h
in any order in a userspace application and you will get the same
ABI. The ABI is guaranteed by UAPI and glibc.
Since fanotify_init requires CAP_SYS_ADMIN in order to work (which usually
means running as root), we need to handle that error case too.

Switch the string benchmarks to using bench-timing.h instead
of hp-timing.h directly. This allows the string benchmarks to
be run usefully on architectures such as ARM that do not have
support for hp-timing.h.
In order to do this the tests have been changed from timing each
individual call and picking the lowest execution time recorded to
timing a number of calls and taking the mean execution time.
ChangeLog:
2013-09-04 Will Newton <will.newton@linaro.org>
* benchtests/bench-timing.h (TIMING_PRINT_MEAN): New macro.
* benchtests/bench-string.h: Include bench-timing.h instead
of including hp-timing.h directly. (INNER_LOOP_ITERS): New
define. (HP_TIMING_BEST): Delete macro. (test_init): Remove
call to HP_TIMING_DIFF_INIT.
* benchtests/bench-memccpy.c: Use bench-timing.h macros
instead of hp-timing.h macros.

LDFLAGS puts the library too early in the command line if --as-needed
is being used. Use LDLIBS instead.

Resolves#15921
The test case nptl/tst-cleanup2 fails on s390x and power6 due to
instruction sheduling in gcc. This was reported in gcc:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58034
but it was concluded that gcc is allowed to assume that the first
argument to sprintf is a character array - NULL not being a valid
character array.
Another example of all the 64bit arches getting the definition via a
common file, but the 32bit ones all adding it by themselves and hppa
was missed.
I'm not entirely sure about the usage of GLIBC_2.19 symbols here.
We'd like to backport this so people can use it, but it means we'd
be releasing a glibc-2.17/glibc-2.18 with a GLIBC_2.19 symbol in it.
But maybe it won't be a big deal since you'd only get that 2.19 ref
if you actually used the symbol ?
There hasn't been a glibc release where hppa worked w/out a bunch of
patches, so in reality there's only two distros that matter -- Gentoo
and Debian.

The mov lr, pc instruction will lose the Thumb bit from the return address
so use blx lr instead.

[BZ #15909]
* sysdeps/unix/sysv/linux/arm/clone.S (__clone): Use blx

This implementation of strlen is faster than the armv6 version for
all string lengths greater than 1 on a Cortex-A15.
