* release/0.7: (33 commits)
  Update for 0.7.8
  svq1dec: call avcodec_set_dimensions() after dimensions changed. Fixes NGS00148
  vp3dec: Check coefficient index in vp3_dequant() Fixes NGS00145
  qdm2dec: fix buffer overflow. Fixes NGS00144
  h264: Fix invalid interlaced progressive MB combinations for direct mode prediction. Fixes Ticket312
  mpegvideo: dont use ff_mspel_motion() for vc1 Fixes Ticket655
  imgutils: Fix illegal read.
  ac3probe: Detect Sonic Foundry Soft Encode AC3 as raw AC3. Our ac3 code chain can handle it fine. More ideal would be to write a demuxer that actually extracts what can be from the additional headers and uses it for whatever it can be used for.
  mjpeg: support mpo Fixes stereoscopic_photo.mpo
  Add a version bump and APIchanges entry for avcodec_open2 and avformat_find_stream_info.
  lavf: fix multiplication overflow in avformat_find_stream_info()
  lavf: fix invalid reads in avformat_find_stream_info()
  lavf: add avformat_find_stream_info()
  lavc: fix parentheses placement in avcodec_open2().
  lavc: introduce avcodec_open2() as a replacement for avcodec_open().
  rawdec: use a default sample rate if none is specified. Fixes "ffmpeg -f s16le -i /dev/zero"
  rawdec: add check on sample_rate
  qdm2dec: check remaining input bits in the mainloop of qdm2_fft_decode_tones() This is neccessary but likely not sufficient to prevent out of array reads.
  cinepak: check strip_size
  wma: Check channel number before init. Fixes Ticket240

Prevent error condition in case sample_rate is unset or set to a negative
value. In particular, fix divide-by-zero error occurring in ffmpeg due to
sample_rate set to 0 in output_packet(), in code:

                ist->next_pts += ((int64_t)AV_TIME_BASE * ist->st->codec->frame_size) /
                    ist->st->codec->sample_rate;

this avoids multiple calls. This is done by adding a null draw_slice()

There were multiple issues, for example might we have to re-run
the decompression when the size of the buffer increased,
we should always use a decompression buffer large enough for
the header (so we do not get stuck when the size is too small).

Treating them like 0 is safest, current code would invoke
undefined pointer arithmetic behaviour in this case.
