mgw: Implement the specific RSIP handling

The RSIP has morphed from a global reset, to a per trunk reset and now
it is possible to reset specific ranges on a trunk. This will be used by
the ISUP filter code in the STP.

For legacy range == -1 will be used. This will reset all endpoints
on the trunk. Use OSMO_MAX on endpoint and number of endpoints in case
number_endpoints is 0.

This code will now free everything from the endpoint to endpoint + range
including endpoint+range.
