Remove the ReferIgnore directive from mod_log_config (Dean's veto).
	Get rid of the array for the 'env=' clause, since it only takes
	a single variable name; use a char * instead.  Check for conditional
	envars by seeing if the condition string is non-NULL rather than
	using a separate Boolean cell.
