Convert ganeti daemons to the three-stage startup

This makes almost all of the daemons show error messages, and not return
until they finished listening on the appropriate sockets.

Masterd is the only one "special", as it doesn't do enough
initialization in the server creation, only later....

Change utils.GenericMain protocol

Currently, GenericMain does a two-staged workflow:

- Check, before forking
- then Exec, after forking

This means we don't have any possibility to treat preparation work
(before the daemon is ready for work) different from the actual work....
