[PATCH] SVNPathAuthz is broken

[Tobias Ringström <to...@ringstrom.mine.nu>]

The SVNPathAuthz directive which was introduced recently is broken in 
the sense that you can only set it to off in the topmost scope in the 
config file, i.e. is not possible to say "SVNPathAuthz Off" in a 
Location block. The following patch fixes the problem and a similar 
problem for SVNAutoversioning, but I don't have time to run the test 
suite etc right now, so I'm posting the patch here instead. I'll commit 
it tomorrow when I know that it passes all tests.

Note that there is at least one problem left, because ls is a lot slower 
than before, even with SVNPathAuthz off.

[[[
Fix the inheritence of SVNPathAuthz and SVNAutoversioning by turning
them into tri-state values (default, on, off).

* subversion/mod_dav_svn/mod_dav_svn.c
  (dav_svn_flag): New tri-state enum.

  (dav_svn_dir_conf): Use dav_svn_flag for autoversioning and
  do_path_authz.

  (dav_svn_create_dir_config): Zero is default for all values now.

  (dav_svn_autoversioning_cmd, dav_svn_pathauthz_cmd): Use
  dav_svn_flag values.

  (dav_svn_get_autoversioning_flag): It's only on if it's explicitly
  set to on.

  (dav_svn_get_pathauthz_flag): If's only off if it's explicitly set
  to off.
