Both the new initctl API and the new pidfile watcher plugin failed to
set CLOEXEC on their sockets. This caused forked-off and exec()'d
children to inherit all these descriptors.

This patch prevents too early start of services depending on other
services. E.g, if service B depends on A then we must wait for A to
signal that it is ready before we allow B to start -- in a Finit based
system A does this by creating, or touching (updating mtime), its PID
file. Services (like A) that support SIGHUP should call utime(), or
utimensat(), on the PID file at the end of their SIGHUP handler.

Old event system has been replaced with a more generic condition
concept. The idea is that finit plugins may provide arbitrary
conditions that services may specify as dependencies that they require
to run.
In order to accomodate this, the service management has been
redesigned to use a state machine.
