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.

Fixes issue1228, issue1229, and partially issue1238.

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.

fe022ce2f8 Fix libx264.c to not drop SEI userdata from x264 encoder. 
Most muxers in ffmpeg ignore the SEI if it is placed in extradata, so instead
it has to be catted to the front of the first video frame.

822d0a6e0c Drop code that attempts to decode frames that are prefixed by junk. 
Too often it ends up decoding random data into noise without detecting
it (for example after seeking of some MP3 data with oddly often occurring
startcode emulation).
