Fix a bug in the authz code, related to issue #2388: if the authz global access check is inconclusive (ie. no decision could be made), access should be denied, not authorized.
Patch by: Joe Schaefer <email@example.com>
* subversion/libsvn_repos/authz.c (authz_global_parse_section): Continue walking the authz config as long as the access is not determined. (authz_get_global_access): Return FALSE if the access could not be conclusively determined.
* subversion/tests/libsvn_repos/repos-test.c (authz): Add a section to the test configuration that triggers the bug. Fix the test loop to actually run all unit tests.
