[Qgis-developer] Remove editing functions from QgsVectorLayer

Personally I'm not a fan of that.

Why don't we make startEditing() return a edit buffer/edit session. So you
could do this:

session = layer.editSession()

This would mean that everyone can keep their own edit buffers and can do
what they want.  Means you could also doing this:

with layer.editSession() as session:

which will commit the features at the end.
