eeedef96bb Introduce the concept of an "address-space" to more cleanly support remote-unwinding 
of multiple address spaces (as might arise for a multi-process debugger, for example).
Impace on existing libunwind users should be minimal:

	unw_init_remote(cursor, accessors);

needs to be changed to:

	as = unw_create_addr_space(accessors);
	if (!as)
	  error;
	else
	  unw_init_remote(cursor, as, as_arg);

where "as_arg" is the argument ("arg") that used to be stored
in the accessors structure.  Everything else is the same.

74fc55a61a Add routines to control caching policy. The caching policy can be set to 
(1) single (global) cache, (2) per-thread cache, or (3) no cache at all.
This is loosely based on a per-thread cache patch by Brian Sumner.
