a valid SOF was found, emulate an EOI.
This allows e.g. to at least decode the available part of incomplete MJPEG frames.

element is valid. Skip the code handling SOS and EOI if not, since it can not
work without a valid AVPicture.
This fixes a crash with mjpeg/smclockmjpeg.avi.1.0 from issue 1240 where the
decoder returned an invalid AVPicture.

Removes some disabled dc_index/ac_index checking code that seems to have had
some undocumented issues and should not really be necessary anymore now.
Fixes from issue 1240 the files mjpeg/smclockmjpeg.avi.1.10 and mjpeg/smclockmjpeg.avi.1.171.

Files with invalid VUI are now rejected like
other invalid SPS are.
Fixes issue1231.

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.

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.

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.

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).
Fixes issue1154.

next_frame_offset are not set, because second field has next frame offset set
but not frame_offset, otherwise this wrongly fetch timestamp for the
second field.

- remove unneeded vlc code < 0 check
- reorder vlc code handling so that the unlikely escape decoding
part comes last
- move overflow check out of the decode loop
- branchless sign conversion
