qdoc: Allow formal parameters in link targets

This update allows qdoc to handle \l commands for linking
to functions, where the formal parameters are included in
the link target.

For example, \l {QWidget::find(QString name)} will only match
a member function of QWidget that has a single parameter of type
QString. The parameter name is not used in the search.
