5388f0b479 Reinitialize the h264 decoder context on every valid aspect ratio 
change, not only size changes.

4693b031a3 Move H264 dsputil functions into their own struct 
This moves the H264-specific functions from DSPContext to the new
H264DSPContext.  The code is made conditional on CONFIG_H264DSP
which is set by the codecs requiring it.

The qpel and chroma MC functions are not moved as these are used by
non-h264 code.

2ce1c2e063 Always reset slice_table. 
Previously, the area of a lost slice would be left at the slice number of the previous
frame which could occasionally match the number of the next slice and thus a non existing
slice could have been used for prediction leading to additional decoding errors in otherwise
undamaged slices.

5b0fb5244d Store intra4x4_pred_mode per row only. 
about 5 cpu cycles slower in the local code but should be overall faster
due to reduced cache use. (my sample though has too few intra4x4 blocks
for this to be meassureable easily either way)

c988f97566 Rearchitecturing the stiched up goose part 1 
Run loop filter per row instead of per MB, this also should make it
much easier to switch to per frame filtering and also doing so in a
seperate thread in the future if some volunteer wants to try.
Overall decoding speedup of 1.7% (single thread on pentium dual / cathedral sample)
This change also allows some optimizations to be tried that would not have
been possible before.
