12e1e83461 lavc: set channel count from channel layout in avcodec_open2(). 
Some decoders (e.g. nellymoser) only set channel_layout and do not set
channel count.

a42aadabc6 lavc: add avcodec_free_frame(). 
Since an AVFrame now has malloced members (extended_data), it must have
a destructor.

c084a975aa lavc: use av_mallocz to allocate AVFrames. 
Otherwise the frame is uninitialized, so avcodec_get_frame_defaults()
cannot determine whether to free extended_data.

a83499b13b lavc: rename the argument of avcodec_alloc_frame/get_frame_defaults 
AVFrame is used for both audio and video, so calling the argument 'pic'
is misleading.

3c6607eb6f avcodec_encode_{audio,video}: only reallocate output packet when it has non-zero size. 
Otherwise realloc would free it, which would result in double free

9524cf79df avcodec: add av_get_audio_frame_duration() function. 
This is a utility function for the user to get the frame duration based on
the codec id, frame size in bytes, and various AVCodecContext parameters.

6699d07480 avcodec: add av_get_exact_bits_per_sample() function 
This only returns bits per sample when it is exactly correct. That is, the
codec contains only raw samples with no frame headers or padding. This applies
to basically all PCM codecs and a small subset of ADPCM codecs.

9b027c0d07 dsputil: set STRIDE_ALIGN to 16 for x86 also. 
This fixes crashes in e.g. PNG decoding with SSE2 enabled. In fact, many
x86 optimizations for codecs assume that our buffer strides are 16-byte
aligned.
