Diego Biurrun 36b38500b6 Check for CONFIG_LIBFOO_DECODER/CONFIG_LIBFOO_ENCODER instead of just
CONFIG_LIBFOO in the external libraries section.
This is more consistent with the rest of the Makefiles, it makes clearer what
is actually implemented and should be advantageous if we implement an external
library encoder where we previously just had the decoder and vice versa.

Alexander Strange 0410ee8f86 H.264: Don't set data_partitioning for invalid NAL_DPA.
Before, the decoder could interpret a corrupt frame
as a NAL_DPA and NAL_DPC, and then start decoding
even if decode_slice_header() returned an error.
This frequently caused crashes.

Måns Rullgård ec62d942ea Fix potentially unaligned accesses in ff_copy_bits()
A pointer should never be assigned a value which may have less than the
required alignment of the target type.  Compilers may assume pointer
values have the required alignment, and emit normal load/store instructions.

Unaligned pointers should use a character type or compiler-specific
type modifiers.

Jason Garrett-Glaser 010f98f96a VC-1/WMV3 decoding: don't clear blocks unless they're actually used.
~8% faster VC-1 decoding.
Possible future optimization: clear blocks after use instead of before, and for
DC-only blocks, only clear the DC coefficient.

Jason Garrett-Glaser 4f717c69ed idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall.
Includes mmx2 asm for the various functions.
Note that the actual idct still does not have an x86 SIMD implemtation.
For wmv3 files using regular idct, the decoder just falls back to simple_idct,
since simple_idct_dc doesn't exist (yet).

Justin Ruggles 0fb6a8b339 Remove the 3-front-channel layout from the list of channel layout
aliases.  Calling this "surround" is confusing and questionable.
