network: add separate log category

the network (mgcp_network.c) part and the protocol part
(mgcp_protoocl.c) share a single loglevel DLMGCP. This
makes debuging hard because when debugging the protocol
we also get the log output from the RTP packets.

assign the network part a private loglevel and keep DLMGCP
for the directly MGCP related code
