Copy openbsc to osmocom-3g (for lack of a better name) to build the vlr_3G
branch of openbsc.git, producing osmo-msc, osmo-sgsn with Iu capabilities and
osmo-bsc_mgcp (now a misnomer) to direct RTP streams.
Add osmo-hlr.
Add osmo-iuh for osmo-hnbgw, and libosmo-ranap dependency of osmocom-3g.
Add libasn1c.
