Multiple WWW-Authenticate headers with "satisfy any;".
If a module adds multiple WWW-Authenticate headers (ticket #485) to the
response, linked in r->headers_out.www_authenticate, all headers are now
cleared if another module later allows access.
This change is a nop for standard modules, since the only access module which
can add multiple WWW-Authenticate headers is the auth request module, and
it is checked after other standard access modules. Though this might
affect some third party access modules.
Note that if a 3rd party module adds a single WWW-Authenticate header
and not yet modified to set the header's next pointer to NULL, attempt to
clear such a header with this change will result in a segmentation fault.
