9b56d5c114 avpacket: Deprecate av_dup_packet 
As documented, `av_dup_packet` is broken by design, `av_packet_ref`
matches the AVFrame ref-counted API and can be safely used instead.

ce70f28a17 avpacket: Replace av_free_packet with av_packet_unref 
`av_packet_unref` matches the AVFrame ref-counted API and can be used as
a drop in replacement.

Deprecate `av_free_packet`.

948f3c19a8 lavc: Make AVPacket.duration int64, and deprecate convergence_duration 
Note that convergence_duration had another meaning, one which was in
practice never used. The only real use for it was a 64 bit replacement
for the duration field. It's better just to make duration 64 bits, and
to get rid of it.

cdf58f0599 avpacket: fix copying side data in av_packet_copy_props() 
Side data count is incremented by by calling av_packet_new_side_data()
in the following loop, setting it explicitly results in the resulting
value being twice what it should be.

85e8192b85 avpacket: Fix error checking in packet_alloc 
Previously the wrong buffer pointer was checked, when buf
instead of *buf was checked. But checking the return value
instead is even better.

1afddbe59e avpacket: use AVBuffer to allow refcounting the packets. 
This will allow us to avoid copying the packets in many cases.

This breaks ABI.

90cfc084e3 avpacket: free side data in av_free_packet(). 
Freeing it in av_destruct_packet(), as is done currently, would mean
that we allow it to be allocated with other means. But that would make
av_packet_new_side_data() unsafe.

Side data is not expected to be large, so copying it if required
shouldn't be a problem.

a0b468f5db Make sure av_new_packet() initializes the data and destruct pointers. 
Some code does call av_free_packet() on failed av_new_packets(), this
prevents the freeing of uninitialized pointers.

cdd8930e6a Move av_packet_*() functions from libavformat/ to libavcodec/, where the 
AVPacket structure now resides also.

thread "Google Summer of Code participation" for additional discussion.
