Comment:

 Totally rework the AudioReencodeBuffer part in transcode

 The fifo mode of transcode got completely messed up with the advent of HLS
 mode for mythtranscode.  The core issue was that the video and audio were
 being consumed in different ways, and were no longer well synced.  The
 video
 was being queued, and the audio just accumulated until the each video
 frame
 was dealt with.  This caused a majority of the video frames to be dropped
 to attempt to resync to the audio, and unnecessarily.

 I changed it to actually queue up the audio buffers, and allow the
 consumer
 to pull from that list up until a given timecode, keeping the audio and
 video
 in sync enough for the existing resync code to deal with it.

 This has so far been tested in fifo mode only, and with no cutpoints.

 Fixes #10199, may affect others as well.

 This may break HLS if audio frame sizes differ between input and output,
 but
 this is being worked on, and should be out shortly as well.
