f0777843c0 Move realpath.c to upstream-freebsd.
This is actually a slightly newer upstream version than the one I
originally pulled. Hopefully now it's in upstream-freebsd it will
be easier to track upstream, though I still need to sit down and
write the necessary scripts at some point.

eb149e954e Adding strcmp tuned for Cortex-A15.
The attached patch provides a new implementation of strcmp for ARM,
using LDRD instead of LDR whenever possible.

For older architectures that do not support LDRD, this implementation
uses the same algorithm as before.

Testing and benchmarking:
* Validation: successfully passes a test that compares different strings
of length 1-128 and offsets 0-8 from a word boundary. Checked on
qemu/A15/A9, ARM/Thumb mode, Big/Little Endian.
* Integration with gcc: no regression on qemu for arm-none-eabi --with-cpu
a15/a9 --with-mode arm/thumb.

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.

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.

AFAIK, bionic only ever provided an implementation of bcmp
for x86, and even then, the code was never actually compiled.
Remove the prototype.

bcmp() has been obsoleted and replaced by memcmp()

fae89fc404 Fix raise(3) so it works in signal handlers.
We could special-case raise(3) in non-threaded programs, but the more
conservative course is to make pthread_kill(3) work in signal handlers
at the cost of a race shared by other C libraries.
