9d777508fa Remove dead code in theora_decode_tables 
Reading 7 bits as an unsigned int can't result in a value exceeding 127.
Accordingly, remove error message (as it'll never be reached).

1a48a57071 Fix Theora decoding bug if loopfilter is completely disabled 
Bug caused by the fact that get_bits(gb, 0) is undefined.
Doesn't affect any streams generated by the official Theora encoder, but such
streams are nevertheless valid.

Fixes decoding of CELT-933dd833-nmr-bandt.ogv.

b32c9ca9a3 h264dsp: merge some asm blocks 
Some code was initializing some xmm registers in one asm block and using them
in the following block, assuming they wouldn't be changed in between blocks.

276df9d821 aacenc: Fix bug in LAME windowing where only one channel got initalized 
I used the same loop counter for the inner and outer initalization loops.
This caused initalization to only run for the first channel. This in turn lead
to any channel other than the first using only short blocks.

fc068f9f27 Fixed DXVA_Slice_H264_Long::BitOffsetToSliceData value. 
The 8 bits offset (nal unit type) should not be added, as the spec says:

"This bit offset is the offset within the RBSP data for the slice, relative
to the starting position of the slice_header() in the RBSP"

This fixes DXVA2 support for intel GPU.
