Jit: Start the Jit when framework signals on first screen draw

Cleanup of delayed start - introduce dvmRelativeCondWait in Sync.c.
Additionally, support for deadman timer to start Jit when no screen draws
happen, and to start immediately when running stand-alone.

Fixed bug in assert variant of libdvm - recent MONITOR change had neglected
to add a new type of exit to the exit stats.
