3faa303a47 rv34: DC-only inverse transform 
When decoding coefficients, detect whether the block is DC-only, and take
advantage of this knowledge to perform DC-only inverse transform.

This is achieved by:
- first, changing the 108x4 element modulo_three_table into a 108 element
  table (kind of base4), and accessing each value using mask and shifts.
- then, checking low bits for 0 (as they represent the presence of higher
  frequency coefficients)

Also provide x86 SIMD code for the DC-only inverse transform.

b5fc571e4f latmdec: Check AudioSpecificConfig length before decoding extradata. 
This is different than a normal get_bits() over read because
decode_audio_specific_config() creates its own GetBitContext.

Fixes Bug 170.

f01f6a8474 gsm demuxer: use generic seeking instead of a gsm-specific function.

3ab7700018 mpegvideo: claim ownership of referenced pictures 
Under certain conditions pictures could be released before they were
returned with frame-threading. Broken mv computation in the upcoming
rv34 frame-threading patch was caused by this.

To prevent contexts from running out of available pictures the loop
releasing "unused" pictures has to be run for B frames too.

This doesn't make the code handle sample rate or upsample/downsample
