* Logger class changes only Now compile-time checking is possible with the help of Nullable Value types. * Misc formatting * Manual optimizations PrintGuestLog PrintGuestStackTrace Surfaceflinger DequeueBuffer * Reduce SendVibrationXX log level to Debug * Add Notice log level This level is always enabled and used to print system info, etc... Also, rewrite LogColor to switch expression as colors are static * Unify unhandled exception event handlers * Print enabled LogLevels during init * Re-add App Exit disposes in proper order nit: switch case spacing * Revert PrintGuestStackTrace to Info logs due to #1407 PrintGuestStackTrace is now called in some critical error handlers so revert to old behavior as KThread isn't part of Guest. * Batch replace Logger statements
