gitweb: Add a per-repository authorization hook.
Add a configuration variable that can be used to specify an
arbitrary subroutine that will be called in the same situations
where $export_ok is checked, and its return value used
to decide whether the repository is to be shown.
This allows the user to implement custom authentication
schemes, for example by issuing a subrequest through mod_perl
and checking if Apache will authorize it.
