Stop allocating backref strings within gsub's search loop

* internal.h: add prototype for rb_reg_search0

* re.c: rename rb_reg_search to rb_reg_search0, add set_backref_str
  argument to allow callers to indicate that they don't require the
  backref string to be allocated

* string.c: don't allocate backref str if replacement string is provided
