Log message:

	* ircd/m_gline.c: create abs_expire() macro to convert an expire
	timestamp from the network into an absolute time, if needed;
	rename expire_off to expire globally, since it now represents an
	absolute expiration time; use expire - CurrentTime in gline
	forwarding statements; in ms_gline(), use abs_expire() to convert
	network expiration timestamp into absolute timestamp; in
	mo_gline(), add CurrentTime to oper-provided expiration offset to
	convert to absolute timestamp

	* ircd/gline.c: assume expire and lifetime arguments to
	gline_add() and gline_modify() are already absolute timestamps;
	send lifetime parameter as an absolute timestamp, but leave expire
	timestamp as relative as first part of a 2-phase update

Tested and seems to have the desired effect.  Note that the treatment of
lifetime is incompatible with the prior version of this G-line patch.
