These either remain from openbsc.git or slipped in while applying recent
patches from openbsc.git and do not belong in osmo-bsc.
Empty out contrib: remove things that are either obviously unrelated to
osmo-bsc, or seem old and/or esoteric.
osmoappdesc.py: drop nitb_e1_configs (and some ws)
Rewire build and includes to libosmo-legacy-mgcp.
Drop osmo-bsc_mgcp and related python tests, now found in osmo-mgw.git.
libosmo-legacy-mgcp is installed from osmo-mgw, hence add the dependency to
jenkins.sh (so far using the pre_release branch).
osmo-nitb becomes osmo-msc
add DIUCS debug log constant
add msc vty, remove nitb vty
add libiudummy, to avoid linking Iu deps in tests
Use new msc_tx_dtap() instead of gsm0808_submit_dtap()
libmgcp: add mgcpgw client API
bridge calls via mgcpgw
Enable MSC specific CTRL commands, bsc_base_ctrl_cmds_install() still needs to
be split up.
This is the first step in creating this repository from the legacy openbsc.git.
Like all other Osmocom repositories, keep the autoconf and automake files in
the repository root. openbsc.git has been the sole exception, which ends now.
