QRegExp is a little hard since there's a lot of code inside Qt *using* 
QRegExp, not just taking it. Also, we've ended up needing regular expressions 
in the bootstrapped programs (qmake, moc, rcc), for which bootstrapping PCRE 
would be a real PITA.

However, yes, we should start to fix those codebases now in Qt 5 so that 
removal in Qt 6 is as simple as removing the class and some #ifdefs.
