Subject: Import QMimeType / QMimeDatabase into QtCore.

History of the development before the import:
ssh://codereview.qt-project.org/playground/mimetypes.git

Mimetype definitions come from shared-mime-info where available (UNIX systems),
loaded using a mmap'ed binary cache generated by update-mime-database.
As a fallback if no cache is found, we parse the raw XML files otherwise.

This makes the MIME type support fast and with very low memory usage on UNIX,
and it makes it easy to use on Windows (no dependency on shared-mime-info,
Qt even includes a freedesktop.xml file to use if none are found on the system).
