* Rewrite scheduler context switch code * Fix race in UnmapIpcRestorePermission * Fix thread exit issue that could leave the scheduler in a invalid state * Change context switch method to not wait on guest thread, remove spin wait, use SignalAndWait to pass control * Remove multi-core setting (it is always on now) * Re-enable assert * Remove multicore from default config and schema * Fix race in KTimeManager
