7eeaa6796b libspeexdec: decode one frame at a time. 
This allows for knowing the output size before decoding even when there is no
header (e.g. FLV). Otherwise we would have to do a preliminary full frame
decode to determine the number of frames-per-packet.

180bf988bc mp3on4: create a separate flush function for MP3onMP4. 
The correct decoder private context needs to be used.
This fixes mp3on4 playback and seeking in avplay.

53c8443ad2 mp3on4: ensure that the frame channel count does not exceed the codec channel 
count.

This also allows for checking output data size based on the actual
number of channel instead of the maximum number of channels.

f507dd067a mp3on4: allocate temp buffer with av_malloc() instead of on the stack. 
Avoids allocating unnecessary memory and ensures proper alignment.

27209bb108 h264: mark some MC functions with av_always_inline instead of inline. 
This actually causes them to be inlined, leading to a significant
speedup (1-1.5% in my measurements).

ce42a04884 vp8: fix up handling of segmentation_maps in reference frames. 
Associate segmentation_map[] with reference frame, rather than
decoding instance. This fixes cases where the map would be free()'ed
on e.g. a size change in one thread, whereas the other thread was
still accessing it. Also, it fixes cases where threads overwrite data
that is still being referenced by the previous thread, who thinks that
it's part of the frame previously decoded by the next thread.

586657c20a lavc: deprecate img_get_alpha_info(). 
It's never been touched or used in any way since it was added in 2003
and only works for PIX_FMT_PAL8, which makes me conclude that nobody's
ever used it.

1baa25c7da shorten: fix end-of-stream decoding. 
enable CODEC_CAP_DELAY to flush any remaining frames in the buffer.

Stop decoding when the FN_QUIT command is found so that a trailing seek table
isn't decoded as a normal frame.

decode all channels in the same call to avcodec_decode_audio3() so that
decoding will not stop after the first channel of the last frame.

Updated FATE reference. More valid audio is now decoded.
