069083a419 ac3enc: clip coupling coordinates during calculation 
This is faster than using the clip_coefficients() function. Also,
clipping the coordinates before determining reuse is better since it
will compare coordinates that are closer to their final encoded values.

7221139ba0 lavc: make avcodec_init() static on next bump. 
It's called from avcodec_register() anyway, so there's no reason for it
to be public.

d55ad59a8a ac3enc: separate exponent bit counting from exponent grouping. 
Move bit counting to the bit allocation function. Move exponent grouping to
after bit allocation. This will allow for adjustment of bandwidth parameters
during bit allocation without having to do exponent grouping multiple times.

9791c02733 Saner RV1/2 initialisation and RV2 header parsing. 
Old version was based on lots of guesswork which had different hacks based on
32-bit version field instead of splitting it into major/minor/micro version.
RV2 picture header parser also had a few places where it deviated from binary
decoder.

9d39cbf6cf avpacket: signal possibly corrupted packets 
Use AV_PKT_FLAG_CORRUPT flag to mark packets that might be incomplete
or have errors. Formats that have a mean to validate their packets
should use this flag to deliver such information instead of silently
dropping the packets.

f5f004bc5a x86: cabac: don't load/store context values in asm 
Inspection of compiled code shows gcc handles these fine on its own.
Benchmarking also shows no measurable speed difference.

Removing the remaining cases in get_cabac_bypass_sign_x86() does
cause more substantial changes to the compiled code with uncertain
impact.

2968bedf12 bink: make IDCT take 32-bit input 
Since IDCT transforming 32-bit input to 8-bit output is unusual and unpractical
for most codecs, move Bink IDCT into separate context. Get rid of an additional
permutation table while at it since SIMD support for Bink IDCT is unlikely to
be implemented in foreseeable future.
Quantisation tables also have to change type to signed for proper
dequantisation of DCT coefficients.
