8fbab7a6c8 rtpdec: Initialize some variables to silence compiler warnings
The warnings are false positives, older gcc versions (such as 4.5)
think the variables can be used uninitialized while they in
practice can't, while newer (4.6) gets it right.

76c40fbef0 rtpdec_vp8: Don't trim too much data from broken frames
Previously, for broken frames, we only returned the first partition
of the frame (we would append all the received packets to the packet
buffer, then set pkt->size to the size of the first partition, since
the rest of the frame could have lost data inbetween) - now instead
return the full buffered data we have, but don't append anything more
to the buffer after the lost packet discontinuity. Decoding the
truncated packet should hopefully get better quality than trimming out
everything after the first partition.

71194ef6a8 rtpdec_vp8: Mark broken packets with AV_PKT_FLAG_CORRUPT
This allows the caller to either include them (and get more packets

The warning is a false positive, but I prefer actually initializing

critical.

09ed8098ff rtpdec_vp8: Make sure the previous packet is returned
This is a bug from c7d4de3d73 - if the previous frame wasn't
returned yet (due to missing the final packets), but we have
enough data of it to return the first partition, we write that into
pkt and set returned_old_frame. That commit forgot returning 0 for
the case where this current packet didn't have the end_packet flag
set.

c7d4de3d73 rtpdec_vp8: Don't return known-broken packets
This is built on the assumption that the first partition of each
VP8 packet is essential for decoding any later packet - if this
partition is broken/missed, the arithmetic coder gets out of sync
and decoding the bitstream in further packet ends up with total
garbage. If packets of a frame are lost, make sure the first
partition is intact (return only this part of the packet, nothing
else), otherwise stop returning data until the next keyframe is
received.

Alternatively, one would simply not return any packets at all
until the next keyframe, if packet loss is detected.

Not all details are implemented, but it's enough for proper
playback as long as there is no packet loss.

Tested to work with the packetizer in gstreamer (which although
uses a different codec name, to clarify that it is still a spec
draft).
