Runlevel and version are state, not actions, so they belong behind
org.freedesktop.DBus.Properties rather than another method each.
Finit also claims org.finit on the system bus when it finds one, so
ordinary D-Bus clients can reach it without knowing about
/run/finit/bus. Opportunistic on purpose: no dbus-daemon is a normal
state for the systems Finit runs on, not an error to report.

The bus can already answer questions and change services, so give
initctl the two things it still did another way: watching signals as
they happen, and getting or setting user conditions.
The dbus tests move with it, split by area rather than one file that
grew every time the library did.
