Reduce the amount of buffering used and eliminate hb_snooze in the encoding pipeline
For HD sources on an 8 core system with hyperthreading, we were using 1.5GB
of ram. Add to that the 600MB x264 uses for rc-lookahead, pushes it north of 2GB.
To reduce our memory usage, the fifo depths have been reduced are are no longer
a multiple of cpu count. Use of hb_snooze has been eliminated in the encoding
pipeline so that performance doesn't fall as a result of the reduced fifo depths.
In sync, each audio and video were given separate threads so that each can wait on
it's respective input fifo without blocking the others. In muxcommon, each stream
being muxed was given a separate thread so that each can wait on it's respective fifo.
This allows the removal of hb_snooze in the sync and muxer work loops. In both sync
and muxer, there is common data that is shared by all threads, so special init
routines allocate this shared data and initialize the threads.
