Adds a new visitor pattern API for creation of visitors which visit
all the style entities (symbols, color ramps, text formats, and
label styles) associated with different objects. Can be used on a
renderer, map layer, or project wide level.
E.g. on a project wide level, allows collection of ALL the style
symbols/color ramps/text settings inside a project, including those
in layouts or annotations!
for QgsVectorLayer, when constructing a layer with a URI which
may be invalid
These may be used for layers where the geometry type/CRS is
known in advance, and where the layer path may not be
initially resolvable. (E.g. layers with a URI pointing to a
non-existant file). It is only ever used if the layer cannot
be resolved, otherwise the actual layer geometry type will be
detected and used for the layer.
For the c++ api dox this expands to "\c nullptr" (the
\c directive indicates a code literal value), and for sipify/Python
it expands to ``None`` (`` is sphinx annotation for literal values)
Makes for nicer dox for both c++ and Python!
For the c++ api dox these expand to "\c true" and "\c false" (the

to control if changes can be saved or not. This signal is emitted before a layer is being saved and if a connected slot marks the canCommit variable as False, the layer will not be saved
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
* create QgsMapLayer::LayerFlags for Searchable, Identifiable and Removable
this brings back the information previously saved in the project node back to the layer node
this will allow to embed this information in layer styles
* skip unexisting flag node to avoid setting wrong value for flag
* mark QgsProject::(set)requiredLayers as deprecated
* better API docs
* use new API in current code
* more docs and more old API fixes
* fix bad conversion
* more old API fix
* add missing SIP_OUT
* s/testFlags/testFlag
* fix var name
* adapt project test to test flags
* remove debug calls
* fixeS
