Back-patch addition of stack overflow and interrupt checks for lquery. Experimentation shows that it's not hard at all to drive the old implementation of "ltree ~ lquery" match to stack overflow, so throw in a check_stack_depth() call, as I just did in HEAD.
I wasn't able to make it take a long time, because all the pathological cases I tried hit stack overflow first; but I bet there are some others that do take a long time, so add CHECK_FOR_INTERRUPTS() too.
