If you had a report query that had a subquery in the fields list, and
that subquery had a LIMIT specifier, then it would be removed which
could break your query. This patch prevents this case from breaking by
ensuring that only a LIMIT that follows the last WHERE in the query is
removed.
If you don't have a WHERE, then it will behave like it always
did, removing all the cases of LIMIT (which would still break a subquery
but this is a) more rare, and b) would require more intelligent parsing
to deal with.
Also adds test cases and function documentation.

Tested with this report:
select biblionumber, (select itemnumber from items where items.biblionumber=biblio.biblionumber LIMIT 1) from biblio where biblionumber<1000;
and it worked like a charm
