Move enums that was part of the Qt namespace to qnamespace.h

This caused some headache wrt documentation, since in order to
generate the proper documentation for the qt namespace
qdoc also needed to parse the headers of gui, which breaks
cross-module linking. (This is because qdoc will actually
generate two almost identical nodes in the code tree; one
from the header files from gui and another from the index file
of gui).

The best fix would maybe be to make it part of
QAbstractTextDocumentLayout, but that will break source compat.
