45f374f428 Update labeling gui and add expression support as data defined value 
- Add QgsDataDefined class
- Add QgsDataDefinedButton class
- Add data defined Python support
- Add standalone SVG selector dialog to QgsSvgSelectorWidget class

- Fix for #4607, show only pertinent fields when setting a data defined value
- Fix for #5048 and #5049, data defined settings are literally used
- Fix for #5726, number formatting does not work for expressions
- Fix for #7755, using bufferSize to enable/disable label buffer is confusing
- Fix for #7779, labels do not register in label collision engine; and for #4719, inactive options in labeling dialog
- Prepare label text's expression upfront when preparing layer; makes rendering much faster
- Change name of 'feature obstacles' to appropriate terminology
