NvServices refactoring (#120)
* Initial implementation of NvMap/NvHostCtrl * More work on NvHostCtrl * Refactoring of nvservices, move GPU Vmm, make Vmm per-process, refactor most gpu devices, move Gpu to Core, fix CbBind * Implement GetGpuTime, support CancelSynchronization, fix issue on InsertWaitingMutex, proper double buffering support (again, not working properly for commercial games, only hb) * Try to fix perf regression reading/writing textures, moved syncpts and events to a UserCtx class, delete global state when the process exits, other minor tweaks * Remove now unused code, add comment about probably wrong result codes
