Introduce GSMTAP categories
When looking at GSMTAP output so far, one is easily overwhelmed by way too much information being presented. A lot of is consists of DUMMY frames, which are probably of lowest interest, ever. A concept similar to the "gsmtap-sapi" of OsmoBTS is introduced, by which the user can configure which particular categories (uplink or downlink control or data, gprs or egprs, ...) he actually wants to see in his logs.
