d57c182d8b Allow QgsRasterIterator to iterate over a raster layer, WITHOUT 
actually fetching the raster block data

This allows for efficient iteration over a "reference" layer, where
you require the block extent/origin/pixel size/etc (but not the
reference layer block data itself!), in order to fetch a block from
a DIFFERENT set of rasters (but keeping these pixel-aligned to the
reference raster).

15e0d873d9 select categories in copy style in legend menu entry 
not working yet, just set the menu entries
QgsMapLayerStyle::StyleCategory has moved to QgsMapLayer to avoid making QgsMapLayerStyle a QObject and they are mostly used in QgsMapLayer

2a72eda514 Improve documentation of QgsRasterLayer constructor 
- baseName is just passed on to the parent constructor to be the display
   name, use a literal string in the example to avoid misunderstanding.

 - Remove stray bullet.

4c84cfa29a Fix a memory leak in classify() + add missing annotations/docstrings 
A pseudo color renderer was getting created in classify() but never deleted.

Spotted by @PeterPetrik

As a bonus switched a for loop from mixed constBegin()/end() usage to range for.

2ed144ac59 Apply clang-tidy readability-avoid-const-params-in-decls fixit 
Checks whether a function declaration has parameters that are
top level const.

const values in declarations do not affect the signature of a
function, so they should not be put there.
