Add mgcp_common.h to libosmo-mgcp-client, to not need to share a header file
with libosmo-legacy-mgcp (nor the upcoming libosmo-mgcp). Both libraries use
the enum mgcp_connection_mode (and a for-loop macro and a string mangling
function), so far declared in mgcp.h, and both mgcp-dev and mgcp-client-dev
debian packages would require this header file to be installed. So far the
mgcp-client-dev lacks this header file, which causes the osmo-msc debian
package to fail building. Ways to solve:
- If both -dev debian packages installed the same header file in the same
place, they would conflict if ever installed at the same time.
- mgcp-client-dev can depend on mgcp-dev, but it seems bad to keep such a large
dependency for just one enum and two helpers.
- Instead, this patch solves this by copying the few definitions to
libosmo-mgcp-client.
Once libosmo-mgcp-client has its own copy of those definitions, it is
fully self-contained and depending builds (osmo-msc deb) will succeed.
Copy the few actually common definitions to new header
<osmocom/mgcp_client/mgcp_common.h>. The nature of this .h is that it may be
shared with future libosmo-mgcp without causing linking problems.
Remove libosmo-legacy-mgcp/mgcp_common.c file from the build of
libosmo-mgcp-client, no longer needed.
Add to new mgcp_common.h:
- enum mgcp_connection_mode;
- for_each_non_empty_line() macro.
- mgcp_msg_terminate_nul() as static function. Its complexity is just above
your average static inline, but being inline is a way to use it in both mgcp
and mgcp_client without linking problems.
Replace for_each_line() use in mgcp_client with for_each_non_empty_line()
(for_each_non_empty_line() replaces for_each_line() and uses strtok_r() instead
of a local reinvention).
mgcp_connection_mode_strs are actually only used in libosmo-mgcp-client, so
rename to mgcp_client_ prefix and move to mgcp_client.c.
BTW, the future plan for upcoming libosmo-mgcp is to use the identical header
file, and keep only one copy in the git source tree. The second copy may be
generated during 'make', to avoid code dup while having two distinct headers.

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.
