Rename QDeclarative symbols to QQuick and QQml
Symbols beginning with QDeclarative are already exported by the quick1 module. Users can apply the bin/rename-qtdeclarative-symbols.sh script to modify client code using the previous names of the renamed symbols.

-// QHashField can be used for doing coarse grained set testing, in
-// cases where you do not expect the set to contain the item. For
-// example where you would write:
-// QSet<QString> strings;
-// for (int ii = 0; ii < mystrings.count(); ++ii) {
-// if (strings.contains(mystrings.at(ii)))
-// qFatal("Duplication!");
-// strings.insert(mystrings);
-// }
-// You may write:
-// QHashField strings;
-// for (int ii = 0; ii < mystrings.count(); ++ii) {
-// if (strings.testAndSet(qHash(mystrings.at(ii)))) {
-// // The string *might* be duplicated
-// for (int jj = 0; jj < ii; ++jj) {
-// if (mystrings.at(ii) == mystrings.at(jj))
-// qFatal("Duplication!");
-// }
-// }
-// }
-// For small lists of things, where the hash is cheap to calculate
-// and you don't expect duplication this will be much faster.
