[Development] Removal of "Trolltech" usages inside Qt

[Giuseppe D'Angelo]

One of the blockers of [1] ("Larger changes for Qt 5") is the clean up
of Trolltech strings/namespaces/etc. inside Qt, which is actually
tracked by several bug reports [2].

That's fine, but was any consensus reached about what to change those
strings to? "qt-project.org"? Should any logic for fallbacks (for
settings, etc.) be present in Qt code? I'd like especially to hear
advice from the Chief Maintainer and the legal team.

Cheers,
