A routing engine that needs to compute multicast spanning trees with
special properties will need to delete old trees. There's already
a function that does this: mcast_mgr_purge_tree().
Make it available outside osm_mcast_mgr.c, and change the name
to follow the naming convention (osm_ prefix) for global functions.
