Ensure that jpeg does not use mbs that could require larger padding.
This might have been exploitable.

instead of either aborting on the assert or crashing due to writing beyond
the array due to insufficient padding.

Huffman-compressed JPEG files, so make it decode those files
(samples are welcome).
This fixes issue 1420

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.

AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

Since decoding is doing from the end and aligned by 16
previous code worked correctly only when picture height was dividable by 16,
otherwise it provides garbage in top lines and truncates bottom.
New code adjusts data[] pointers taking in account alignment issue.
