avformat/mxfdec: fix and enhance RIP KLV length checks
...
KLV length is BER encoded (variable size), but the code assumed the encoding to
always use 4 bytes.
Fixes parsing Random Index Pack in samples/MXF/issue2160/PW0805A0V01.4C5B5636.EFA330.mxf.

avformat/mxfdec: guess wrapping of tracks by other tracks with the same body sid
...
This affects the following samples:
samples/ffmpeg-bugs/roundup/issue1775/av_seek_frame_failure.mxf
samples/ffmpeg-bugs/trac/ticket1957/16ch.mxf
samples/ffmpeg-bugs/trac/ticket5016/r0.mxf
samples/ffmpeg-bugs/trac/ticket5016/r1.mxf
samples/ffmpeg-bugs/trac/ticket5316/hq.MXF
samples/ffmpeg-bugs/trac/ticket5316/hqx.MXF
Some AVPacket->pos values are changed because for frame wrapped tracks we point
to the KLV offset and not the data.
