[patch][ccla] dojox.charting.TouchZoomAndPan double tap zoom does not always work on Android

[cjolif]

There are two reasons for this:

• The first one is a dojo.gesture bug. See #12981

• The second one just happens when another tap action takes a long time. In this case no touchend will be fired but a touchcancel instead. This not reproducible on simple example but can be seen on moibleChart demo when double tapping in the data indicator mode. The workaround is the avoid doing the length action in the touchstart but delay it.

This patch also contains little AMD cleanups.
