[PATCH] osmo-mgw[master]: protocol: allow wildcarded DLCX

[dexter]

Review at  https://gerrit.osmocom.org/4227

protocol: allow wildcarded DLCX

In many cases it is simpler to instruct the mgcp-gw to drop all
connections at once instead of removing each connection
individually.

drop all connections and release the endpoint in when no connection
id is supplied with the DLCX command.
