Layer2 Wireshark integration

Hi! I've recycled the old GSMTAP wireshark plugin that I originally wrote for project airprobe. Using this patch (now in our git tree as well, applies against current wireshark svn) and the layer2 host program as well as the l1test.bin target program, you can watch BCCH messages in realtime. The architecture is like this: * DSP forwards decoded normal burst data to layer1/sync.c * layer1/sync.c generates L1A_L23 protocol message and sends it via the SERCOMM HDLC layer over RS232 * "osmocon" receives the HDLC frame and relays it to the Unix domain socket * "layer2" receives the L1A_L23 protocol message on the Unix domain socket, adds a GSMTAP header and sends it to the GSMTAP UDP port on localhost * wireshark captures on the 'lo' interface and calls the GSMTAP dissector plugin for everything received on the GSMTAP UDP port number.
