Replace macro checks with actual symbol checking

This increases a little more the check time, but is also more precise.
It is also required for cases where qfeatures.h incorrectly reports
support for a feature, but the actual class is not compiled (the case
for a couple of classes in Qt Simulator).

Additionally, the macro has been made more concise, and is reused for
both QtGui and QtNetwork.
