Martin Storsjö c4584f3c1f rtpenc: Allow packetizing H263 according to the old RFC 2190
According to newer RFCs, this packetization scheme should only
be used for interfacing with legacy systems.

Implementing this packetization mode properly requires parsing
the full H263 bitstream to find macroblock boundaries (and knowing
their macroblock and gob numbers and motion vector predictors).

This implementation tries to look for GOB headers (which
can be inserted by using -ps <small number>), but if the GOBs
aren't small enough to fit into the MTU, the packetizer blindly
splits packets at any offset and claims it to be a GOB boundary
(by using Mode A from the RFC). While not correct, this seems
to work with some receivers.

Martin Storsjö 34056cbba5 Fix a crash in the H.263 RTP packetizer
If size == 1 and buf[0] == 0 and buf[1] == 0 (the first byte after the
buffer), it would set size = -1 and crash in the later memcpy.

rtpenc_*.c files.
