[Dovecot] Redundant timers

Hello.

I am on an irrational crusade against unneeded timers (it started as a well-meaining power saving exercise), and I have now started removing polling in Dovecot.

Attached is a patch with the work I did on this the other night. Would something like that be acceptable, or should I make it in a different way?

There seems to be no one-shot timer support, right?

Is there a Dovecot coding style document? (I did notice that there appears to be an 80 char width that I exceeded)

Cheers, Anders
