Initial MiracleCast Implementation

This initial commit contains the main "miracled" daemon that does
link-management and peer-discovery/control. The "miraclectl" tool can be
used to control this daemon during runtime.

Note that this implementation is still missing a lot of stuff. All it
currently does is provide link-management and basic peer-discovery.
Following commits will hook everything else up.

The actual Miracast/Wifi-Display related runtime control is not being
worked on, yet. Feel free to use the proof-of-concept from the OpenWFD
repository. The MiracleCast implementation will not get any such
functionality unless the basic link-management is properly working.
