Rework MAME integration a bit 

The periodic callback is now used as a way to service "commands" sent from the main thread
Upon servicing a command, the mame thread will set the current command to NO_CMD then wait for the main thread allow the mame thread to continue
During this wait, the main thread may optionally set the next command (done here for STEP -> VIDEO), ensuring the next callback will service that command
A dummy "WAIT" command can be sent to trigger this waiting behavior, allowing the main thread to safely touch mame while the mame thread is frozen (important for mem accesses and probably savestates?)

A/V sync is also reworked. We can assume that 1/50 of a second worth of samples will be sent each sound callback. We can also assume 1/FPS of a second worth of time will be advanced each frame advance
So, we can just give hawk 1/FPS worth of samples every GetSamplesSync, if they are available. If we have less (probable on first few frames), we'll just give all the samples, and hope it balances out later.
