(Complete) Update Patch

Allright, here is the complete patch for updates. The three changes in
mod_dav_svn, are there as a hack to temporarily solve the anchor/target
problems we have been having with ra_dav.

The rest are genuine problems with the way updates work.

Note: svn up --nonrecursive is still not implemented. I may get to it in a
little while
