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.

QtCore now exports a couple of functions to the other Qt modules: qTopLevelDomain,
a helper function for QUrl::topLevelDomain(); and qIsEffectiveTLD(), a helper
function for QNetworkCookeieJar.

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.
