6524d3cad7 unistd.h: don't include sys/capability.h 
Don't pull in unnecessary header files. AFAIK, I've fixed all
the code which didn't include the correct header files.

5b349fc22e Adding memcpy tuned for Cortex-A15. 
The strategy for large block sizes is LDRD and STRD with offset addressing,
where the main loop copies 64 bytes in every iteration, (i.e., 8 calls to
LDRD and STRD pairs), interleaving load and stores (i.e., the pairs of LDRD
and STRD of the same data are consecutive instructions), and the writeback
of an updated address is a separate instruction, which allows us to write
back the accumulated update once per iteration.

This strategy is implemented in memcpy.S. In some configurations, a plain
version of memcpy (included from memcpy-stub.c) is used instead of the
optimized one.

Validation:
* Correctness: checked memcpy using a test harness for block sizes
ranging between 1 to 128, and source and destination buffers alignment
ranging in { 0,1,2,3,4,8,12 } bytes each.
* Performance: benchmarking on Cortex-A15 FPGA indicates that this strategy
is better for A15 than the strategy used by glibc and even slightly better
than using NEON. Benchmarking on Cortex-A9 bare metal and Linux shows
that the proposed strategy is reasonable: not as fast as the version of
memcpy from glibc (which is the best open source strategy for A9), but
comparable with csl and bionic.
* Integration with GCC: no regression for arm-none-eabi --with-cpu
cortex-a15 and cortex-a9.

7c83a1ed81 Break bionic implementations into arch versions. DO NOT MERGE 
Move arch specific code for arm, mips, x86 into separate
makefiles.
In addition, add different arm cpu versions of memcpy/memset.

7c0dd555c0 libc: create sys/capability.h 
Per "man capset", sys/capability.h is the appropriate header file
for the capget / capset definition, not unistd.h. Fixed.

As a short term hack, continue to include sys/capability.h in
unistd.h, until we can fix all the code which uses capget / capset.

701bec2af3 Reimplement scandir(3). 
The old scandir implementation didn't take into account the varying
size of directory entries, and didn't correctly clean up on its
error exits.
