	stop here.  Don't initialize mbs_case.  Set valid_raw_len.
	Use mbs_allocated instead of MBS_* macros.
	(re_string_construct): Don't initialize stop and valid_len here.
	Don't initialize mbs_case.  Use mbs_allocated instead of MBS_*

	no translation and set in that case valid_raw_len as well.

	len/stop.  Clear valid_raw_len and offsets_needed when clearing
	valid_len.  Use mbs_allocated instead of MBS_* macros.
	Check original offset against valid_raw_len instead of valid_len.
	Remove mbs_case handling.  Adjust valid_raw_len together with
	valid_len.  If is_utf8 and looking for tip context, apply
	pstr->trans first.  If buffers start with partial multi-byte
	character, initialize mbs array as well if mbs_allocated.
