[Qgis-developer] new QgsDebugCall macro

[Sandro Santilli]

I've pushed a new debugging macro for use to simplify tracing of
functions enter/exit events.

Use like this:

 void QgsMapToolNodeTool::canvasPressEvent( QMouseEvent * e )
 {
   QgsDebugCall;
   ....
 }

To get (with debugging builds) log messages like this:

 Debug: src/app/nodetool/qgsmaptoolnodetool.cpp: 348: (canvasPressEvent) Entering.
 Debug: src/app/nodetool/qgsmaptoolnodetool.cpp: 348: (canvasPressEvent) Leaving.

With non-debugging builds there will be no overhead.
