	posix          : regexec.c 

Log message:
	(match_ctx_clear_flag): New function.
	(sift_ctx_init): Likewise.
	(update_cur_sifted_state): Likewise.
	(add_epsilon_src_nodes): Likewise.
	(sub_epsilon_src_nodes): Likewise.
	(check_subexp_limits): Likewise.
	(search_subexp): Likewise.
	(sift_states_bkref): Likewise.
	(merge_state_array): Likewise.
	(sift_states_iter_bkref): Remove unused function.
	(add_epsilon_backreference): Remove unused function.
	(re_search_internal): Adapt new members and interfaces.
	(check_matching): Check the back references in initial states
	if they are really match null string in the initial state.
	(proceed_next_node): Change the evaluation of back references,
	since we have real registers here.
	(set_regs): Adapt new interface of proceed_next_node.
	(sift_states_backward): Add invocation of update_cur_sifted_state
	instead of add_epsilon_backreference.
	Add a sentinel to the outermost while loop.
	Move the handling of back references to sift_states_bkref function,
	since we can't handle some back references (e.g. a back reference
	which match NULL string) here.
	(transit_state_mb): Handle the new member max_mb_elem_len.
	(transit_state_bkref_loop): Move the evaluation of back references to
	search_subexp function, since we can't evaluate some back references
	(e.g. a back reference which can have plural matchings) here.
	(match_ctx_init): Adapt the new member.
	(match_ctx_add_entry): Adapt the new members.
