Fix Frame Advance and FifoPlayer pause/unpause/stop.
CPU::EnableStepping is not atomic but is called from multiple threads
which races and leaves the system in a random state; also instruction
stepping was unstable, m_StepEvent had an almost random value because
of the dual purpose it served which could cause races where CPU::Run
would SingleStep when it was supposed to be sleeping.
FifoPlayer never FinishStateMove()d which was causing it to deadlock.
Rather than partially reimplementing CPU::Run, just use CPUCoreBase
and then call CPU::Run(). More DRY and less likely to have weird bugs
specific to the player (i.e the previous freezing on pause/stop).
Refactor PowerPC::state into CPU since it manages the state of the
CPU Thread which is controlled by CPU, not PowerPC. This simplifies
the architecture somewhat and eliminates races that can be caused by
calling PowerPC state functions directly instead of using CPU's
(because they bypassed the EnableStepping lock).
This is the only way to get Wiimotes working under Android now.
This, just like the Wii U Gamecube Controller Adapter, completely goes around Android's limitations and talks with the device directly through USBManager.
Couple notes.
Continuous scanning must be enabled otherwise the Wiimotes won't be seen.
The UI doesn't expose support for this yet. One must change the Wiimote source and continuous scanning settings manually.
Testing up to two wiimotes in Taiko No Tatsujin, no reason to believe all four won't work.
