svnbrowse: Use svn_ra_get_dir2() instead of svn_ra_list(); It allows us to skip

resolving revision (it would automatically fallback to HEAD if
SVN_INVALID_REVNUM is passed). It also does not require a receiver callback and
the resulting information is more specific.

* subversion/svnbrowse/svnbrowse.c
  (list_cb): Remove function.
  (state_create): Use new API and walk the hashtable to put everything into an
   array; we cannot use the hashtable directly becuase we need it to be
   accessible by a numeric consecutive index (for selection).
  (view_draw): Don't treat first item as "go up"; we'll implement this later.
