Here's my first cut.  It basically moves nearly all of the pause and
speed change logic into one place in the decoder loop.  It could go
pretty much anywere in the loop but the very top seems most logical.

I've only done limited testing so far.  I will do more this weekend,
but it should be close enough for others to provide feedback.  There
might be a very tiny race condition, but I think it should be
inconsequential, and if it turns out not to be, it will hopefully be
much easier to fix now.

Finally, I have chosen to ignore the waitvideo paramter to NVP::Pause
and the unpauseaudio parameter to NVP:Play for now.  I'm need to look
at how and why they are needed before reimplementing them.
