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!
- call reserve on container classes where applicable
- make sure Q_FOREACH uses references
- remove dynamic casts to base classes
- fix some implicit bool conversions
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!

This reverts commit fe9461be05043daf34057a85e57424f99eeae43d.
The commit was originally added for a label based feature which needed
to be reworked after recent labeling changes. Reverting this commit
to avoid polluting the API.
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.

- 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

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.
Allows composer map grid annotations in custom formats which are
evaluated using QgsExpressions. Made possible through the use
of Expression Contexts(tm)!
