use separated libosmo-mgcp-client, apply rename to mgcp_client_*

After osmo-mgw changes I8e0b2d2a399b77086a36606f5e427271c6242df1 and
I99f7faab637cfcc22ece64a1dbcbe590f2042187, apply linking of new
libosmo-mgcp-client and renames to drop the "gw" from mgcp_client_*.

Also rename the gsm_network.mgcpgw to mgw, to indicate that the MGCP client is
used to contact the MGW (Media Gateway).

Depends: I8e0b2d2a399b77086a36606f5e427271c6242df1 (osmo-mgw)
         I99f7faab637cfcc22ece64a1dbcbe590f2042187 (osmo-mgw)
