(unw): Remove debug_level.

Browse source 
(tdep_debug_level): Declare it as a separate variable.  This
	ensures that only one debug-level variable is in use
	at any given time, no matter what combination of
	local-only vs generic and static vs. dynamic libraries
	are in use.
(unw): Document why it's not an UNW_ARCH_OBJ().
