av_destruct_packet() always frees the packet data even when the demuxer
is going to re-use it, thus causing crashes when decoding audio
frames (as implemented in a pending patch).

av_free_packet() is used instead, as it allows each demuxer to set the
right packet data releasing mechanism through the pkt->destruct callback.

* qatar/master:
  fft: init functions with INIT_XMM/YMM.
  pcmenc: set frame_size to 0.
  gsm demuxer: use generic seeking instead of a gsm-specific function.
  gsm demuxer: return packets with only 1 gsm block at a time.
  avcodec: add GSM parser
  doc: Replace ffmpeg references in avserver config file by avconv.
  doc: Fix names of av_log color environment variables.
  Fix a bunch of platform name and other typos.
  Add some missing changelog entries and release 0.8_beta2
  No longer build libpostproc by default
  wtv: fix memleaks during normal operation
  threads: add CODEC_CAP_AUTO_THREADS for libvpx and xavs

Timecode can be specified with a negative value in MOV...

This indicates that the actual frame size is based on the buf_size passed to
avcodec_encode_audio().

This fixes some cases where the clipping was entirely missing.

This reverts commit 0efd48df.
Reason for the revert is that the code seems based on some

Since packets all contain only a single block, the generic seek function can
be used while still maintaining block-accuracy.

fixes stream copy of raw gsm to mov.
tested with QuickTime.

The WAVE demuxer returns packets with many blocks per frame, which needs to be
parsed into single blocks. This has a side-effect of fixing the timestamps.

Under certain conditions pictures could be released before they were
returned with frame-threading. Broken mv computation in the upcoming
rv34 frame-threading patch was caused by this.

To prevent contexts from running out of available pictures the loop
releasing "unused" pictures has to be run for B frames too.

Fixes Libav Bug 195.

This doesn't make the code handle sample rate or upsample/downsample
change properly but this is still a good sanity check.
