Another bit in the project refactoring work to get rid of dependencies
on QgsProject singleton.
Reading of layer trees from XML is now split into two phases:
1. read XML and keep layer IDs
2. resolve layer IDs to QgsMapLayer instances (using QgsProject)
There are convenience methods to do both phases in one go.
spell check will be done automatically in words by default (when some conditions are fulfilled)
possibility to avoid in words checking by adding :* at the end in spelling.dat
one can add #spellok at the end of a line of code to skip spell check on this line

- Checking/unchecking a group doesn't change the check state of its children.
A node is visible if and only if it is checked and all its parents too.
- There is no more a semi-checked state for a group
- Ctrl-clic on a unchecked group will check the group and all its descendants.
- Ctrl-clic on a unchecked layer will check the lager and all its parents.
- Ctrl-clic on a checked group will uncheck the group and all its descendants.
- Ctrl-clic on a checked layer will uncheck the layer and all its parents.
- Those actions are available in contextual menu items in the tree view.
- Invisible layers because they or their parent(s) is unchecked are greyed out.
To make the implementation saner, the legend node that may be embedded within parent
layer node is kept separately from activeNodes.

- 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.
This adds a new "edit symbol" item to the right-click menu for a
renderer child legend item (eg categories for the categorised
renderer). Selecting it opens a symbol editor dialog which allows
for directly editing the classes symbol. It's much faster than
opening the layer properties and going through the style tab.
Allows toggling on/off all the symbol items for categorized/graduated/
rule based layers via the right click menu on an item. Previously
you'd have to manually toggle each item one-by-one.
Fix#13458
This introduces two new options to filter legend elements:
- filter by expression: a boolean expression can be set. Only symbols of
features that make the expression evaluated to true will be kept in the legend
- filter by polygon: only symbols of features that are inside the given
polygon will be part of the legend.
The polygon filtering is used in particular for a new option in the
composer legend that allows to filter out anything that is not included
in the current atlas polygon.
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!
