Similar to libswscale this does resampling and format convertion, just for audio
instead of video.
changing sampling rate, sample formats, channel layouts and sample packing all
in one with a very simple public interface.

recovery points that have non-zero recovery_frame_cnt resulted in
flagging incomplete frames as keyframes. This delays setting the
keyframe flag till the frame has been fully constructed.

More locally and globally consistent.

That was clumsy and confusing, only show the descriptive channel
layout string.

This is mainly useful for filters (like the sox synth), which
overwrite the content of the passed data.

The new syntax is more extensible and more user-friendly.

This breaks the previous syntax, should not be an issue as possibly
no-one is already using anullsrc.

Original code had the assumption of only one FLV packet per RTMP packet. But that assumption is incorrect for higher bit rates. Made changes to the code to accommodate more than one FLV packet per RTMP
+packet.

rv34_decode_slice() can return without allocating any pictures.

This may (or may not) cause problems with files that have no keyframes.

Partially fixes bug 44.

pixel_format/video_size only apply to 'rawvideo' (==uncompressed) demuxer
and make no sense for the other raw (== containerless) demuxers. Keep
only the framerate option for those.

Also use unique classes for all raw video demuxers
