the checkbox form widget
In QGIS 2.x we always displayed the underlying raw value of a field
using the checkbox widget in the attribute table or in identify results
(i.e. the text display of the field would always match the value
the user had set for the checked or unchecked representation status,
e.g. "yes"/"no", "present"/"absent", etc)
This was changed in 3.0 so that the representation status ONLY affected
how the underlying stored values are mapped to a boolean true or false
value, and accordingly the attribute table/identify results started
only showing "true" or "false" strings.
This new setting allows users to control whether they want plain text
displays of the field to use the 3.x "true"/"false" behavior (the
default), or if they want to see the 2.x style actual field value.
Fixes#21986
plus:
- fix multiple string keys with commas in value relation widget
- more robust JSON and array (un)marshalling
- uniform array representation in value relation widgets
- lot of test coverage
- automatic QVariant type conversions in JSON utils
- nodes() return the list of all nodes
- findNodes<T> returns a list of the nodes matching the class
Also drops the regexp for finding form attrs in the value-relation
expressions.
Other minor fixes as suggested in the PR review.
The value relation widget filter expression can now use two
new functions/variables that have access to the current
values and geometry of the form being edited.
This allows for dynamic filtering (drill-down) as explained
in the crowdfunding page:

The new functions/variables are:
Function:
get_current_form_field_value( 'FIELD_NAME' )
Variable:
@current_form_geometry
