Previously only geotiff format was available, even though the
underlying QgsRasterFileWriter/GDAL libraries support other
formats.
This commit exposes those other formats to the dialog so that
users can directly save rasters to them (including everyone's
new BFF, geopackage).
...by moving extra arguments to new LayerOptions structs. This allows
us to more easily add new layer constructor options without making
the API cumbersome to use.
when changing current band
Now the widget asks users if they want to delete existing categories
when they switch a band, just like how the categorized renderer
widget asks when the categorized field is changed.
number of bands. Will be useful for porting raster analysis code
to use QgsRasterBlock instead of GDAL calls.

This is necessary in order to be able to correctly translate between absolute and relative paths
deeper in the code - e.g. paths to SVG files used in marker or fill symbols.
Until now, relative paths were translated to absolute paths on the fly.
This is now changed - paths to files should be always absolute within QGIS objects - and paths
only get turned into relative when saving projects. When loading a project, relative paths
are translated to absolute paths immediately.
This should lower the overall confusion about relative/absolute paths within QGIS, and also
allow having different base directories for relative paths (e.g. QML or QPT files may use relative paths
to their directory - rather than to the project directory)
Instead of progress changed signals on the provider/layer level,
instead use QgsFeedback arguments for methods which previously
emitted progress changed signals
from a raster layer
Adds an easy way to style discrete rasters such as landuse classes
using the Paletted renderer. Just select the Paletted renderer,
pick a band, then hit the "Add Unique Values" button. The unique
pixel values will be fetched from the layer and a color assigned
to each using the currently selected color ramp.
