Initial support for export + curses-visualization of measurements
This extends osmo_nitb to offer a UDP feed of real-time measurement reports, which can be used by (a variety of) external tools for visualization or other processing. We also add a small ncurses based tool (meas_vis) which shows a baragraph display of the last few mobile stations that were active, indicating their uplink/downlink receive level and quality. <WARNING> This sends non-portable structures like gsm_meas_rep over UDP and assumes the receiver has identical alignment and endianness! Before this feature is merged, it either needs to be converted to a unix domain socket (but they don't do multicast, which would be nice) or the wire format needs to change into something portable with defined alignment and encoding </WARNING>
