Ask the RA layer to switch a working copy to a new revision and URL.

This is similar to svn_ra_do_update3(), but also changes the URL of every node in the target tree to a child of the @a switch_url. In contrast, update changes only the revision numbers, leaving any switched subtrees still switched.

@note Pre Subversion 1.8 svnserve based servers always ignore ancestry and never send copyfrom data.

@since New in 1.8.
