 * D-Bus client for Feral GameMode (com.feralinteractive.GameMode).

 * Calling requestStart() tells the daemon to apply performance
 * optimizations (CPU governor, I/O priority, GPU perf mode, etc.)
 * for the calling process. requestEnd() reverses them.

 * GameMode is optional — if the daemon is not installed the calls
 * are silently ignored.
