Per suggestions by Roy T. Fielding:

 - remove Match directive, allow Require to be negated
 - rename <Match*> directives to <Require*>
 - rename <RequireNotAny> to <RequireNone>
 - disable <RequireNotAll>
 - rename MergeAuthz to AuthMerging and change its arguments to Off|And|Or

Also convert text formatting macros into functions, and revise
authz_core_check_section() so that check for non-negative directives
follows De Morgan optimization.
