Fix issue #2353, commit switched error "missing or not locked".

* subversion/libsvn_client/commit.c
  (svn_client_commit3): since svn_wc_get_actual_target doesn't do the
   right thing in all cases, lets stop using it.  instead, just check
   to see if the target path is a directory, and if it is, add it to
   the correct array of dirs to lock.  then, split off the parent dir
   so we can chop it up and lock its components.

* subversion/tests/clients/cmdline/switch_tests.py
  (test_list): remove XFail from commit_mods_below_switch.
