I introduced a regression in KDNSSD for 5.79.0 which results in crashes on 
startup or whenever zeroconf activation happens, reportedly at least for 
knotes, ktorrent & kfourinline, but surely also any other KDNSSD-using 
application, due to a bad pointer casting in central classes.
See https://bugs.kde.org/show_bug.cgi?id=432949

Commit 8c14803908a2a718fa0716fb98506aebda1fed46 fixes that, with first 
confirmations, by reverting the cause which was a change from static_cast to 
(macro-blurred, but no real excuse) reinterpret_cast.

David, can you please do a 5.79.1 KDNSSD release with that commit cherry-
picked? Given this crash is happening during startup of some apps, so one 
cannot even disable zeroconf usage in the UI as temporary workaround where 
possible, it is a rather grave experience for those affected.

Cheers
Friedrich
