Make sure that all uses of max_length in the test suite use values smaller than 255. If we use max_length > 255 the test suite can't be run on MySQL 4.

Fixed #10182 -- Corrected realiasing and the process of evaluating values() for queries with aggregate clauses. This means that aggregate queries can now be used as subqueries (such as in an __in clause). Thanks to omat for the report.

This involves a slight change to the interaction of annotate() and values() clauses that specify a list of columns. See the docs for details.
