exp2 is faster.

It may be possible to optimize further; e.g the exponents seem to be
multiples of 0.25. This requires study though.

The change was not correct and broke H264

This reverts commit cd83f899c94f691b045697d12efa21f83eb2329f.

If that is the case, the loop setting predictor_state in
sonic_decode_frame causes out of bounds reads of int_samples, which has
only frame_size number of elements.

exp2 suffices here. Some trivial speedup is done in addition here by
reusing results.

This retains accuracy, and in particular results in identical values
with GNU libm + gcc/clang.

sample benchmark (Haswell, GNU/Linux):
proposed : 424160 decicycles in pow_table,     512 runs,      0 skips
exp2 only: 1262093 decicycles in pow_table,     512 runs,      0 skips
old      : 2849085 decicycles in pow_table,     512 runs,      0 skips

arc4random() was designed as a superior interface for system random
number generation, designed for OpenBSD and subsequently incorporated by
other BSD's, Mac OS X, and some non-standard libc's. It is thus an improvement to
use it whenever available.

As a side note, this may or may not get included in glibc, and there is
a proposal to create a posix_random family based on these ideas:

Tested on Mac OS X.

  h264: do not call frame_start() for missing frames

Not merged, FFmpeg does a lot more in frame_start to setup missing frames
as well (like coloring them), and the overhead of the other setup is
minimal.
