Add FDEventMonitor for monitoring file descriptors

Add FDEventMonitor helper thread for monitoring file descriptors for
events (ready for read, ready for write) without the need for spawning
a separate thread with a tight loop around poll()/select().

FDEventMonitor uses an eventfd for signaling poll() instead of a
timeout, therefore it can sleep for long times in case of no events but
still immediately respond to e.g. shutdown.
