[or-cvs] Permit transitioning from ORPort=0 to ORPort!=0, and back.

Update of /home2/or/cvsroot/tor/src/or
In directory moria:/home/arma/work/onion/cvs/tor/src/or

Modified Files:
	config.c 
Log Message:
Permit transitioning from ORPort=0 to ORPort!=0, and back.

This is actually a bit more subtle, because we need to rotate
the dnsworkers and cpuworkers if certain options (logs, orport, etc)
change. Maybe set_options() should detect this and notify the caller
that it should rotate them.

Expect some mysterious crashes.
