Apparently we've got Unknown Object (Phabricator User) in
translation project now.
Not sure how it became invalid, but automated scripts
better be robust for this.
- Make it work with repositories outside of svn.b.o.
Useful for local debugging.
- Make it aware of svn subpath repository setting.
So now it's possible to restrict commit rights
to a subpath in svn repository.
- Make SVN repositories always available for
read-only access;
This script only generates content of either svnroot-access
or svnroot-authfile (depending on command line arguments).
It's not directly usable yet and would need some magic to
make it able to pass the data to svn.b.o. But this is up to
machines setup, not to the script.
