osmo-mgw: refactor endpoint and trunk handling
The trunk and endpoint handling in osmo-mgw is still very complex and
implemented in various places (mostly mgcp_protocol.c). Also we use
still integers for endpoint identification, which is not flexible enough
to address timeslots/subslots on an E1 trunk. Some refactoring is needed.
- get rid of integers as endpoint identifiers, use strings instead and
find the endpoint based on its string name on the trunk.
- identify the trunk based on the trunk prefix given in the endpoint
name.
- refactor trunk and endpoint allocation. Aggregate functionality in
in mgcp_endp.c and mgcp_trunk.c. Also remove non-reusable code that
relates to the still exisiting, but unfinished E1 trunk support.
- refactor rate counters, put them into a separate module and do no
longer allocate them per trunk. Allocate them globally instead.
