4c09dd6429 (intern_regions): Allow for empty region-list.

	sequential address.
(unwi_dyn_remote_find_proc_info): Allocate "di" dynamically (it needs to persist
	until put_unwind_info() is called).

1fc6f4e6b3 (unwi_dyn_remote_find_proc_info): If anything goes wrong, return -UNW_ENOINFO. 
Skip over "prev_addr".  Read start/end-IP directly into the "di" structure,
	not into temporary variables.  Skip padding by directly adjusting the
	address (don't bother fetching padding values; that only slows things down).
	Return 0 only if we really did find dynamic unwind info.
