openldap/servers/slapd/result.c
Kurt Zeilenga 0dbaf87730 Another round of changes behind -DSLAPD_SCHEMA_NOT_COMPAT 
plus these changes unhidden changes:
	remove now meaning --enable-discreteaci configure option
	fix ITS#451, slapd filters
	Add ber_bvecadd() to support above
	constify ldap_pvt_find_wildcard() and misc slapd routines
	renamed some slap.h macros
	likely broken something
