Neels Hofmeyr 97df691307 separate libosmo-mgcp-client from mgcp server code 
When osmo-mgw is built --with-mgcp-transcoding, linking the mgcp library
also requires linking libgsm, even though e.g. osmo-msc never use it.
Separate the MGCP client code from the MGCP server code to avoid this dep.

The mgcp client code does use some definitions from mgcp.h and mgcp_common.c.
For simplicity, link mgcp_common.c in both libosmo-legacy-mgcp as well as
libosmo-mgcp-client. That means it is not possible to link both
libosmo-legacy-mgcp and libosmo-mgcp-client in the same binary because of
duplicate symbols, but currently that is sufficient. (An alternative would be
code dup or yet another libosmo-mgcp-common library.)

Add libosmo-mgcp-client to debian packaging.

About OsmoMGW
=============

OsmoMGW originated from the OpenBSC project, which started as a minimalistic
all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached
maturity and diversity (including M3UA SIGTRAN and 3G support in the form of
IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one
approach to fully independent separate programs as in typical GSM networks.

OsmoMGW was one of the parts split off from the old openbsc.git. It originated
as a solution to merely navigate RTP streams through a NAT, but has since
matured to a Media Gateway implementation that is capable of streaming RTP for
2G (AoIP) and 3G (IuCS) GSM networks as well as (still not implemented at time
of writing) transcoding between TRAU, various RTP payloads and IuUP.

The OsmoMGW program exposes an MGCP interface towards clients like OsmoMSC and
OsmoBSC, and receives and sends RTP streams as configured via MGCP.

The libosmo-mgcp-client library exposes utilities used by e.g. OsmoMSC (found
in osmo-msc.git) to instruct OsmoMGW via its MGCP service.

The libosmo-mgcp library exposes MGCP server utilities used by e.g. OsmoBSC-NAT
(found in osmo-bsc.git) to navigate RTP streams through a NAT.
(At time of writing, this is still called libosmo-legacy-mgcp.)
