[Development] templates as QObjects

[Peter Kümmel]

After the "noise" here "real" code:

https://qt.gitorious.org/~syntheticpp/qt/qt4/commit/c1b839494d90e8c1a93b0dd2e08a2a365095d89f

Based on Qt 4.8.2.
moc creates a header when it finds a template, if not then nothing changes.
(It builds Qt with the patch, but it's a hack in the parser)


In summary

   Foo<int> foo1;
   Foo<int> foo2;
   Foo<double> foo3;

   // works
   QObject::connect(&foo1, SIGNAL(asignal(T)), &foo2, SLOT(aslot(T)));


   // this should be possible, but string matching fails
   // no problem in Qt5
   QObject::connect(&a, SIGNAL(asignal(int)), &foo1, SLOT(aslot(T)));


   // this should not be possible, but it runs because of the (void*) casts in the background
   // maybe catched in Qt5
   QObject::connect(&foo1, SIGNAL(asignal(T)), &foo3, SLOT(aslot(T)));


It's only an experiment, to see what could be done without using clang.

Maybe I bring it up at the QtCS.
