uhd: Added controlport interface for UHD sink's "command" message handler.
Also added an example, usrp_sink_controller.py, to excercise this
feature. Fixed up the source example, too, to better manage parsing
options and setting the UHD source block alias (defaults to 'gr uhd
usrp source0', which is the default for any flowgraph with a single
UHD source block).
