As the subject says, this puts AVPacket in line with AVFrame, allowing
easier extensibility of the struct, and preventing some corner cases when
packets are used uninitialized on stack. Compared to V1, i included the entire
set here, plus a few changes to ffplay and avformat/utils.
This removes all av_init_packet() instances in the tree, and all uses of
AVPacket on stack i could find. It's not exhaustive, as i probably missed a
few, but they can be removed any time between the deprecation of public
sizeof(AVPacket) and it's removal 2+ years from now.
Then there's the few cases where an AVPacket is part of another public struct,
as is the case of AVPacketList, or attached_pic in AVSteam. The latter i could
adapt right now, but it would mean a lot of preprocessor checks littering the
codebase until removed, so i refrained from doing so.
FATE passes, but a few of these patches are untested as FATE doesn't cover
some of these modules.
