Joachim Wiberg dd1390a6c2 initctl: monitor and condition control over the bus
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.
