Make the image orientation only optionally applied for TIFF images
to match the new image handler flags.
The default however remains to apply transformation, as opposed
to JPEGs.
The patch also adds the capability to write metadata orientation.

The TIFFReadRGBAImageOriented method turns out to return colors with
alpha premultiplied by default. The only reason we pass our own tests
is because we also save the colors incorrectly unpremultiplied.
The patch fixes the format type of the returned images, and explictily
writes the how alpha should be interpreted in the saved files.

Split reading TIFF headers from the decoding to make it
possible to read correct metadata on undecoded images.
This fixes reading the image format from the QImageReader,
and is necessary for later patches.

We currently save all non-indexed images as RGBA TIFF files. We should
save them without an alpha channel, to save space and maintain the
information that they are opaque.

We write TIFF files using big-endian RGBA, by using the RGBA8888 QImage
format we can remove the manual conversion done in qtiffhandler.
