4a05bef4c0 Cache the most-recently used timezone for mktime_tz and localtime_tz.
Normally, the C library implicitly caches your timezone by virtue
of the fact that the prehistoric API assumes a single timezone for
the entire process.

The unfortunate mktime_tz and localtime_tz extensions work around
this, but represent timezones as strings to their callers, so code
that makes heavy use of these needs a cache to be able to perform
acceptably until it can hopefully one day be rewritten to use
java.util.Calendar or icu4c.

cdb27f239b Upgrade to tzdata2013b.
From the release notes:

  Changes affecting current and future time stamps:

    Haiti uses US daylight-saving rules this year, and presumably future years.
    This changes time stamps starting today.  (Thanks to Steffen Thorsen.)

    Paraguay will end DST on March 24 this year.
    (Thanks to Steffen Thorsen.)  For now, assume it's just this year.

    Morocco does not observe DST during Ramadan;
    try to predict Ramadan in Morocco as best we can.
    (Thanks to Erik Homoet for the heads-up.)

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.
