Optimise storage/calculation of geometry bounding boxes #2824

Commits on Feb 21, 2016

  1. Optimise storage/calculation of geometry bounding boxes 

    - removes storage of bounding box from QgsPointV2 (gives significant
decrease in size of object)
- more efficient calculation of bounding box for linestrings

Additionally, this commit moves the bounding box invalidation to a
virtual QgsAbstractGeometryV2::clearCache() method, so that other
non-bounding box caches can also be cleared when the geometry
is modified.
