This is possible now that the next-API is gone.

Those are private fields, no reason to have them exposed in a public
header. Since there are some (semi-)public fields located after these,
even though this section is supposed to be private, keep some dummy
padding there until the next major bump to preserve ABI compatibility.
Otherwise it might happen that invalid dimensions are used when reading
a video packet; this might lead to undefined overflow.

The mlv demuxer supports input split into multiple files; if invalid
data is encountered when parsing one of the subsequent files, that file
is closed. But at this point some index entries belonging to this file
might already have been added. In this case, the read_packet function
might try to use the AVIOContext (which is NULL) to read data which will
of course crash. This commit fixes this.

A negative bits_per_coded_sample doesn't make sense.
If it is too large, the size calculation for av_get_packet overflows,
resulting in allocation of a too small buffer.
Also make sure width and height are sane.
