bab7a911b2 [API] Add new map layer class "QgsGroupLayer"
A group layer is a map layer which consists of a set of
child layers, where all component layers are rendered as a single
flattened object during map renders.

This commit sets up the base framework for QgsGroupLayer only
(i.e. no rendering changes).
