QGAL: avoid having to re-calculate lists of variables

Change the functions solvePreferred() and solveExpanding() to take a
list of variables, so they don't need to calculate them based on the
list of constraints. That way, the trunk variables are calculated only
once.

This commit also reduce the scope of 'sizeHintConstraints' variable
instead of clearing and reusing it.
