The reason is this is easier for PIC code (in particular on darwin...).
Keep the old names as pointers (static in cabac_functions.h so gcc
knows these are just immediate offsets) so the c code can nicely stay the same
(alternatively could use offsets directly in the functions needing the
tables). This should produce the same code as before with non-pic and better
code (confirmed) with pic.

The assembly uses the new table but still won't work for PIC case.

The assembler may fail to place literal pools close enough to
instructions referencing them.  An explicit .ltorg directive

libschroedinger is the preferred way to decode Dirac video.

This allows masking CPU features with the -cpuflags avconv option
which is useful for testing different optimisations without rebuilding.

This feature is complex, of questionable utility, and slows down

This removes all references to AVCodecContext.dsp_mask and marks
it for eviction at the next version bump.  It has been superseded
by av_set_cpu_flag_mask() which, unlike this field, works everywhere.

General cosmetics, such as keeping lines under 80 characters,
fixing a couple of typos (predition -> prediction) and a
general style fix that was pointed out by Derek when I was having
my sliced multithreading patch in review by him.

libavcodec/xxan.c:293:13: warning: variable ‘corr_end’ set but not used

This simplifies the code a bit and avoids an uninitialized variable warning.

Fixes jittery video playback of rm files with cook audio.

This also allows dropping some PPC-specific ugliness from dsputil.[ch].

This fixes the warning:
libavcodec/mpegaudiodec.c:1704:14: warning: variable ‘out_size’ set but not used

This improves output for formats with more than one AVCodec.

Do not pointlessly call ff_alloc_packet multiple times,
and fix an infinite loop by clamping the maximum
number of bits to target in the algorithm that does
not use lambda.

Recent register allocation changes (x86inc.asm update) changed the
register order and thus opcodes for the inner loops. One of them became
>128bytes, which confuses other parts of this function where it jumps
to fixed-offset positions to extend the edge by fixed amounts. A simple
register change fixes this.

Fixes ac3-encode and eac3-encode FATE test failures with SSE2 disabled.
