The improvement allows immediate cancellation of raster rendering
in progress. Until now, even when map rendering got cancelled
(e.g. by zooming of panning canvas), the GUI got blocked while waiting
for raster layers to finish their rendering (only vector layers have
had support for cancellation). This should allow for much smoother
user experience while browsing maps including rasters.
The cancellation is supported currently by WMS/WMTS and WCS providers.
GDAL provider may also get support thanks to improvements in GDAL 2.

- rename methods with XML to Xml, CRS to Crs, WMS to Wms, ID to Id
- rename methods with SRS to Crs
- rename methods with abbreviations like "dest" to "destination"
- rename methods with abbreviations like "src" to "source"
Now all classes and members are either exposed to bindings or marked
as "not available in Python bindings" in the docs.
Drop test thresholds to 0. Now it should be much easier to determine
what missing members have been added which are causing test
failures.
Rationale:
- there was a lot of large objects passed by value, so potentially
there's a speed bump from this
- even for implicitly shared classes like QString/QList there's still
a (small) cost for copying the objects when there's no reason to
- it's the right thing to do!

[BUG] #8417 incorrect value loaded from netcdf file
The data has not be loaded incorrectly, but QGIS doesn't apply scale
and offset defined for each band.
This commit will apply scale and offset to GDAL Provider BandStatistics
and to RASTER block of data.
It also adds bandScale and bandOffset method to QgsRasterDataProvider Python API.
