[Qgis-developer] QGIS 3

[gordon at shieldaig.com]

I am all for moving ahead.

I was checking out another application with `valgrind` on Ubuntu 17.04 
64-bit so thought I would give `qgis` a try eg.

valgrind --leak-check=full ./output/bin/qgis

Is this only with my build (simply entering and exiting the qgis 
application) or does it affect anyone else?  Are there better tools?
