This moves some stuff out of the main loop for the unaligned case.

This is a partial revert of c435f06b,
since it didn't actually fix the original problem with shallow clones.
It returns just a hash, not something we (currently) can extract as a
version string in the form things are expecting.

Revision control will remember it for us forever.

I'd commented out mine and stuck azanelli's code in for testing,
 and then accidentally committed it like that.

We were assuming that LDR, LDRD, and STRD could be used on
 unaligned addresses, but this turns out not to be true on really
 old hardware.

This will be removed shortly, but at least it should be correct
 before it goes.
Makes the code get used unconditionally (when uncommented), and
 actually frees the buffer it allocates (now using the libopus
 allocation functions).

The different results for surround were mostly due to a bug in squishyball.

This also splits the rate adjustment between SILK and CELT (previous
code only changed SILK)

Intensity stereo is now based on equiv_rate and should no longer oscillate
in hybrid mode. Also, there is now a separate set of thresholds for
surround tuned by Monty. The non-surround thresholds were also updated at
low bitrate to be closer to what Monty found for surround.

This removes an unused definition warning when compiling without
 custom modes.

Still needs more tuning

Don't include the generated celt/arm/celt_pitch_xcorr_arm-gnu.S in the
dist tarball, but do include its celt_pitch_xcorr_arm.s source file.

Automake's dependency tracking seems to be confused by our asm
generation double-indirection. It's sufficient to have just
CLEANFILES = $(CELT_AM_SOURCES_ARM_ASM:.s.in=-gnu.S)
to fix the error about 'armopts-gnu.S' not being cleaned, but
celt_pitch_xcorr_arm-gnu.S is also not cleaned without raising
a warning. Therefore we explicitly clean both sets of ARM_ASM.

These are all completely untested.
