Norman Feske f274ed549e gui_session: distinguish view-stacking operations
This patch eliminates the use of invalid view handles as special
Session::Command arguments. The TO_FRONT and TO_BACK operations
interpreted as invalid neighbor as top-most or back-most position.
Those corner cases are now expressed via dedicated commands. The
new stacking commands are FRONT, BACK, FRONT_OF, and BEHIND_OF.

While changing the command interface, the patch removes the OP_
prefix from the opcode values.
