When importing writerfilter, we change to oox when
importing images. This transition doesn't store any
previous contexts and all instances are reset. The
problem occurs when we have identical images because
the transition erases all caches we have to determine
if an image has already been imported or not, which
causes that we import the same image multiple times
which create unnecessary copies.
This introduces the XGraphicMapper, which can be used
to store the XGraphic for a key and can be transferred
between writerfilter to oox. With this we can remember
which images were already imported and don't create
unnecessary internal copies which decreases memory.
This also includes a test which checks that the import
and export doesn't produce unnecessary copies of
identical images. The test checks that for OOXML, ODF
and MS Binary formats.

The code is just used in vcl from LO's POV.
This way we can drop the dtrans directory and get rid of yet an
other library.

This is preparing to change how GraphicManager works where it
won't base itself around GraphicObject anymore but Graphic. No
functional or cosmetic change was made to the classes, only
changes that were needed because of the move and rename.
The only thing that wasn't moved is the GraphicRenderer as it
is not needed in vcl for now (but makes sense to move it in the
future to keep graphic stuff together).
grfmgr was renamed to GraphicObject as the GraphicManager will be
changed a lot and most likely moved out, so the name grfmgr won't
make any sense anymore.
All the UNO implementations were renamed with a prefix Uno and
used the same name as the class name. This is made to be more
specific which are the Uno objects (for example graphic.cxx
contained the implementation of XGraphic, which is similar to
graph.cxx contains Graphic).
