mgcp_client: make domain part of endpoint configurable
So far, both osmo-msc and osmo-bsc always pass endpoint names of the form
'...@mgw' to osmo-mgw. Allow configuring the 'mgw' part.
Note that the actual way to pass a differing name is to pass a composed
'rtpbridge/*@foo' to mgcp_msg_gen() in the struct mgcp_msg. So this merely adds
a common VTY config for the domain name part, changes to clients are necessary.
- add mgcp_client_rtpbridge_wildcard() (useful for AoIP endpoints)
- add mgcp_client_endpoint_domain() (useful for SCCPlite endpoints)
- add mgcp client vty cfg 'mgw endpoint-domain NAME'
Rationale: reading pcaps becomes so much easier when each of osmo-bsc and
osmo-msc address their MGW with differing domain names. Otherwise, both will
have a '0@mgw' endpoint and it gets really confusing.
Also: our MGCP clients osmo-bsc and osmo-msc use code dup to compose the
initial 'rtpbridge/*@mgw' rtpbridge wildcard. It should be defined by this API
instead.
This will be used by:
* osmo-msc I87ac11847d1a6d165ee9a2b5d8a4978e7ac73433
* osmo-bsc I492023e9dca0233ec0a077032455d9f2e3880f78
After these, with according configuration, there can be a '0@bsc' and a '0@msc'
endpoint on two separate osmo-mgw instances:
osmo-mgw-for-bsc.cfg:
mgcp
domain bsc
osmo-bsc.cfg:
msc 0
mgw endpoint-domain bsc
osmo-mgw-for-msc.cfg:
mgcp
domain msc
osmo-msc.cfg:
msc
mgw endpoint-domain msc
There can also be '0@bsc' and '1@msc' endpoints on one single osmo-mgw instance with:
osmo-mgw.cfg:
mgcp
domain *
and same osmo-{bsc,msc}.cfg as above.
(By default, everything will still use '@mgw')
