split off osmo-mgw: remove files, apply build, rename 

Add vty and logging previously used from libcommon

Rename libmgcp to libosmo-legacy-mgcp and install.

Use DLMGCP, not DMGCP.

Slim down the public mgcpgw_client API, move all elements not actually used by
current callers to private headers / static c.

Depends: libosmocore I09c587e2d59472cbde852d467d457254746d9e67

/* A number map assigns a "random" mapped number to each user provided number.
* If the same number is requested multiple times, the same mapped number is

*
* Number maps plug into possibly shared pools and expiry queues, for example:
*
* mapA -----------+-> pool1 <-+-- mapB
* {10->1, 11->5} | {1, 2, 3, ...} | {10->2, 11->3}
* | |
* | |
* /-> \-> expiry1 <-/
* | (30 seconds)
* |
* mapC -------+-----> pool2 <-+-- mapD
* {10->1, 11->3} {1, 2, 3, ...} | {10->2, 11->5}
* |
* expiry2 <-/
* (60 seconds)
*
* A map contains mappings ("10->1"). Each map needs a number pool, which can
* be shared with other maps. Each new mapping receives a number from the pool,
* which is then unavailable to any other map using the same pool.
*
* A map may point at an expiry queue, in which case all mappings added to it
* are also appended to the expiry queue (using a separate llist entry in the
* mapping). Any number of maps may submit to the same expiry queue, if they
* desire the same expiry timeout. An expiry queue stores the mappings in
* chronological order, so that expiry checking is needed only from the start
* of the queue; hence only mappings with identical expiry timeout can be added
* to the same expiry queue. Upon expiry, a mapping is dropped from the map it
* was submitted at. expiry_tick() needs to be called regularly for each expiry
* queue.
*
* A nr_mapping can be embedded in a larger struct: each mapping can have a
* distinct destructor (del_cb), and each del_cb can figure out the container
* struct's address and free that upon expiry or manual deletion. So in expiry
* queues (and even maps), mappings of different container types can be mixed.
* This can help to drastically reduce the amount of unnecessary visits during
* expiry checking, for the case that no expiry is pending. An expiry queue
* always knows which mappings to expire next, because they are right at the
* start of its list.
*
* Mapping allocation and a del_cb are provided by the caller. If del_cb is
* NULL, no deallocation will be done (allowing statically allocated entries).
