(struct ia64_proc_info): Delete.

Browse source 
(struct ia64_cursor): Change type of "pi" member from struct ia64_proc_info to
	unw_proc_info_t.
(struct unw_addr_space): Declare "acc" member even for UNW_LOCAL_ONLY case.
(ia64_acquire_unwind_info): Delete
(ia64_relesae_unwind_info): Ditto.
(ia64_find_proc_info): New routine.
(struct ia64_unwind_table_entry): Delete.
(struct ia64_unwind_talbe): Ditto.
(struct ia64_global_unwind_state): Remove "unwind_table_pool" member.
(ia64_get_proc_info): Rename to ia64_make_proc_info().
