In this case it means replacing a packet in the muxer's context by
a pointer to an AVPacket, namely AVFormatInternal.pkt.
Because this packet is freed generically, one can remove the muxer's
deinit function.

This is possible now that the next-API is gone.

The libwebp_animencoder returns a single packet with the entire animated
stream, as that's what the external library produces. As such, only ensure the
stream was produced by said encoder (or propagated by a demuxer, once support
is added) when attempting to write the requested loop value.
Fixes ticket #9179.

When the trailer is never written (or when a stream switches from
non-animation mode to animation mode mid-stream), a cached packet
(if existing) would leak. Fix this by adding a deinit function.

The WebP muxer sometimes caches a packet it receives to write it later;
yet if a cached packet is too small (so small as to be invalid),
it is cached, but not written and not unreferenced. Such a packet leaks,
either by being overwritten by the next packet or because it is never
unreferenced at all.
Fix this by not caching unusable packets at all; and error out on
invalid packets.

This is the 1st patch in preparation for using WebPAnimEncoder API for encoding
and muxing WebP images.
