OpenBSC GPRS status update

Hi all! As some of you may have noticed, there are some references to GPRS in the openbsc 'master' branch now. The code in there is sufficient to configure a nanoBTS via OML and RSL (SI13) to establish contact with an existing NS-over-IP capable SGSN. All that needs to be done is to set a couple of parameters at the BTS level in openbsc.cfg. I've documented them briefly in the wiki (VTY reference page). Also, at least one of your timeslots have to be of PDCH pchan type. We don't implement dynamic TCH/PDCH switching yet. As the changes required to get this initialization/configuration done are non-invasive, I decided to include them in the master branch right away. If you set 'gprs enabled 0' in your openbsc.cfg, all GPRS functionality should be disabled. This is of course only the first step. The much bigger work will be in the grps-sgsn branch, where work will continue on completing the BSSGP and LLC protocol implementations and the actual SGSN + GGSN functionality. The goal is of course to eliminate the need for an external SGSN/GGSN completely.
