The original workaround was only supposed to apply to QList/
QVector of QVariantMaps. By replacing them all in sip we
break mapping of signals defined in c++ which are emitted
by Python code.
Fixes exceptions after running processing algorithms in Qt6
builds.
And transparently map requests for grass7 provider to grass provider
It's misleading putting an old version number in the provider name,
when this provider supports grass versions 8 +
Use the safer method of explicitly including the provider type
when storing layer sources to string in more places, which eg
fixes running the copied qgis_process string when a non gdal
layer source is used for a raster layer. Also fixes the same
situation when restoring an algorithm from the history log.
Fixes#54264
And make sipify handle this nicely. This means that all our non-flag
style enums correctly map across to IntFlag python enums on Qt 6,
fixing issues with negative enum values for these and providing
a better match for the original c++ enum.
