45b7bd7c53 h264: disallow constrained intra prediction modes for luma. 
Conversion of the luma intra prediction mode to one of the constrained
("alzheimer") ones can happen by crafting special bitstreams, causing
a crash because we'll call a NULL function pointer for 16x16 block intra
prediction, since constrained intra prediction functions are only
implemented for chroma (8x8 blocks).

d483bb58c3 ac3dsp: do not use pshufb in ac3_extract_exponents_ssse3()

e6d9fa66f1 ac3dec: Move center and surround mix level tables to the parser. 
That way all mix levels as exported by avpriv_ac3_parse_header()
will have the same meaning.

Previously the 3-bit center mix level for E-AC-3 was used to index in a
4-entry table, leading to out-of-array reads.
