Subject:  - patch a reference picture leak in ffmpeg/libavcodec/mpegvideo.c
 that caused aborts on h264 transport stream encodes.  - patch the log level
 of some h264 decoder error messages so we don't fill our log with messages
 about stuff that's a very likely & not terribly significant.  - don't let
 hb.c set the ffmpeg av_log level to AV_LOG_DEBUG -- it fills the HB activity
 log with junk.  - add a count of the decoder errors to decavcodec's final
 report.  - when we don't have any chapter text (i.e., during a typical cli
 encode) just print the chapter number rather than empty quote marks.
