[PATCH] introduce AuthzSVNRepoRelativeAccessFile configuration item for mod_authz_svn

Dear Subversion maintainers,

We would like to avoid having to mention each of our subversion
repositories inside an Apache configuration, so we use SVNParentPath.

However, this currently means we can only use a single authz
configuration file. We'd like to be able to have a different file for
each repository, to increase isolation.

We've implemented a patch that allows this, by introducing a new
Apache configuration directive:

      D. Example 4: Per-repository access file

         This configuration allows to use SVNParentPath but have
         different authz files per repository.

         <Location /svn>
           DAV svn
           SVNParentPath /path/to/reposparent

           AuthType Basic
           AuthName "Subversion repository"
           AuthUserFile /path/to/htpasswd/file

           AuthzSVNRepoRelativeAccessFile on

           Require valid-user
         </Location>

         NOTE: AuthzSVNRepoRelativeAccessFile on causes the authz file
         to be read from /path/to/reposparent/<repo>/conf/authz

Is this something that might be included in subversion?

[[[
Implement AuthzSVNRepoRelativeAccessFile to allow SVNParentPath to use
a different authz configuration file for each repository.

* subversion/mod_authz_svn/mod_authz_svn.c
  (get_access_conf) Check if AuthzSVNRepoRelativeAccessFile is on, and
  if so, load the conf/authz file from inside the repository being
  accessed rather than one which is statically configured in the
  Apache configuration.
  (subreq_bypass, access_checker, check_user_id, auth_checker)
  Recognise that it's valid not to have a AuthzSVNAccessFile if
  AuthzSVNRepoRelativeAccessFile is used.
