bus: Fix timeout restarts
The code counting pending fds relied on restart of timeouts when they are
enabled. This patch adds function that ensures that such enabled timeouts
have their timekeeping data reset (and not only when timeout is
registered into event loop processing).

When timeouts weren't reset, they'd fire at rather random and mainly
incorrect moments leading to interruption of connections of dbus-daemon.

Every time we reset the interval, we also need to re-enable the timeout
and mark its end time to be recalculated by the event loop, so combine
the old set_enabled(TRUE) with set_interval() as a new restart() method.
This leaves all the set_enabled() calls having a FALSE parameter, so
remove the parameter and rename the method to disable().

[smcv: fix minor coding style issues]
[smcv: replace set_reenabled()/set_interval() pair with restart()]
[smcv: replace set_enabled(FALSE) with disable()]
