[01/34] kernelshark: Fix modelReset() signaling, rename update to updateGeom

Commit Message

Fix segfault introduced by the migration to Qt6.

There was a public update() function in KsGLWidget class which overrides
QWidget::update(). The QAbstractTableModel::modelReset signal was connected
to the QWidget::update slot using "old" connect syntax. This was working
since QWidget::update was declared as a slot, and registered in QWidget
meta information.

When migrating to Qt6, the new connect syntax was used, which accidentally
connect the KsGLWidget::update function instead of QWidget::update.
