* Savestates: Enable "Start Paused" by default
* Emu/rsx/IO: Resume emulation on long START press
* rsx: fix missing graphics with savestates' "Start Paused" setting
* rsx/overlays: Add simple reference counting for messages to hide them manually
* Move some code in Emulator::Pause() so thread pausing is the first thing done by this function
In order to make input more "atomic" I added man in the middle interfaces to decrease the delay between input and cellPad.
But I failed to notice that this introduced a data race between both ends of the pipeline.
I hope the new mutex location doesn't cause any noticeable input lag.
While usually not exposed to the user, there was a slight chance that user input was read in a dirty state.
This became apparent during usage of the new pressure sensitivity button
