99797 .obj/qtldurl.o 

>From the commit message:

   Add QUrl::topLevelDomain() and move TLD table from QtNetwork to QtCore
    
    Move Qt's copy of the Mozilla public suffix list from QtNetwork
    to QtCore and use it to expose a new API function QUrl::topLevelDomain().
    This function returns the section of the url that is a registrar-controlled
    top level domain.
    
    The motivation for this new API is to allow QtWebKit implement a Third-Party
    Cookie blocking policy. For this QtWebKit needs to know the element of the url
    that is the registry-controlled TLD. Without this knowledge it would end up
    blocking third-party cookies per host rather than per registry-controlled domain.


How odd.
