595324e143 Completely remove INIT_VLC_USE_STATIC, it is deprecated since ages and

2f9bbdd25c Change VLC table creation in x8_vlc_init to use INIT_VLC_USE_NEW_STATIC.

c05df6895f Use ff_msmpeg4_decode_init to initialize ff_msmp4_mb_i_vlc since static 
VLC tables should only be initialized from one place.
This initializes/calculates more VLC tables than necessary for VC1 decoding,
but this is only done once and only a small overhead in time and space (maybe
30 kB) it seems not worth adding a separate function.

10_vorbis_submap_indexes.patch by chrome.
I am applying this even though Reimar had some comments to improve it as it fixes
a serious security issue and I do not want to leave such things unfixed.

138fe83215 Perform the DC prediction reversal immediately after decoding all of 
the DC coefficients. This has a greater probability of leveraging the
coefficients while they are still cached.

When testing with the Big Buck Bunny 1080p video, I consistently saw
improvements of 500k-600k dezicycles per run (through
reverse_dc_prediction()) thanks to this move.
