Initial import from the monolithic Qt.

This is the beginning of revision history for this module. If you
want to look at revision history older than this, please refer to the
Qt Git wiki for how to use Git history grafting. At the time of

If you have already performed the grafting and you don't see any
history beyond this commit, try running "git log" with the "--follow"
argument.
