......................................................................
mgcp_ratectr: refactor rate counter and set group name
The rate counter group is currently only referenced by an index. In a
system with multiple trunks this makes it difficult to say which rate
counter group belongs to which trunk sinde the index that is used does
not necessarly corespond to a specific trunk.
Since rate counter groups can now get a human readable name assigned, we
should do that.
Also E1 specific rate counters only make sense for E1-trunks, so they
should not be present on the virtual trunk.
