f75f4194d1 Restructure av_log_missing_feature message 
Some invocations include a verb in the log message, others do not.  Yet
av_log_missing_feature expects callers to provide a verb.  Change the
function to include a verb instead and update the callers accordingly.
The result is a more natural function API and correct English in the
function invocations.

37f701f1c3 avcodec: allow either planar or interleaved sample format when encoding mono 
When there is only 1 channel, the planar and interleaved formats of the same
data type should be treated as identical.

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.
