Rationale:
- there was a lot of large objects passed by value, so potentially
there's a speed bump from this
- even for implicitly shared classes like QString/QList there's still
a (small) cost for copying the objects when there's no reason to
- it's the right thing to do!
The writing of data-defined properties to XML was using invalid data.
Also fixes a possible memory leak in assignment operator.
Thanks Nyall for help tracking it down!

If selected, then the images output by composer will include only
the area of the composition with content. There's also an option
for margins to add around the item bounds if required.
If the composition includes a single page, then the output will
be sized to include EVERYTHING on the composition. If it's a
multi-page composition, then each page will be cropped to only
include the area of that page with items.
A new image export options dialog has been added to facilitate
this, which also includes handy shortcuts for overriding the
print resolution or exported image dimensions.

This is +/- equivalent of QgsFeatureRendererV2 for vector layer labels

- Main C++ core and gui classes and desktop app integration
- Support for authentication method plugins
- Does not contain any integration with service connections
The feature can be toggled individually for groups - in layer tree view context menu.

- QgsPalLabeling now internally uses new engine
- label/diagram providers can hook into rendering loop to avoid extra feature loops
- map rendering uses the new engine instead of QgsPalLabeling

Now used instead of QgsPalLabeling for labels/diagrams
This code has been funded by Tuscany Region (Italy) - SITA (CIG: 63526840AE) and commissioned to Gis3W s.a.s.
The idea is to make the engine more flexible compared to QgsPalLabeling implementation:
- abstract dealing with text labels / diagrams from the engine itself
- allow multiple types of labels per layer
- support custom label providers (e.g. implemented by plugins)
- make the labeling engine independent from map rendering engine
- make it easier to auto-test the labeling engine and its components

- New expression functions for area(geom), perimeter(geom),
point_n(geom), start_point(geom), end_point(geom), make_point(x,y)
- Add new variant to length() function which takes a geometry object,
allows for length(geom) evaluation.
- Rename x_at, y_at to $x_at, $y_at (alias old names) to reflect that
these only work on current feature geometry
- Add x(geom), y(geom) functions which return x and y coordinate
for point geometries or centroid x/y for non-point geometries
(fix#11008)
Previously only the option to limit the scale range of the scaling
was available. Now you can also choose to limit the corresponding
rendered size in mm.
