Convert db_controller to a generic event consumer

Will also rename the program, as it will act as system's generic event
dispatcher. Event and event handler bindings are static for now, but
this will problably change.

Use zmq_recv() in dedicated thread in db_controller.

It seems Python can only do signal processing in the main thread.
If the main thread calls zmq_recv(), no exceptions get raised
when a SIGINT is received for example.

WIP:
This moves the zmq_recv() to a separate thread, while the main...
