Of course we know the fix. mod_authz_svn reads the entire authz INI
file into memory for every request. All we need to do is

   1. write a function in mod_authz_svn.c which verifies whether a user
has read access to an entire tree. That's just a matter of looping over
all paths in the authz file which prefix-match the tree.

   2. invoke this function on the source path of any COPY request.

Pretty easy stuff. Personally, I think we should do it. COPY requests
(svn cp URL1 URL2) are relatively rare, and we can document the fact
that mod_authz_svn places a bit of a damper on O(1) copies.
