Before this PR, we had several implementations of a relational model. The form view used the BasicRelationalModel, which was a wrapper around the BasicModel. The list view used the RelationalModel (a simpler version that didn't support complex usecases of x2many fields). The kanban view used the KanbanModel, an extension of RelationalModel. This PR removes all these, and replaces them by a single model. It is called RelationalModel, and as a similar structure as its predecessor (with datapoints). It now handles tricky x2many usecases of the form view though. This PR also comes with several important changes: 1) The new model is based on unity reads [1]. This means that all data required by the view is fetched at once, and datapoints are created with their data (whereas before, they were responsible to fetch their data). There's an exception for special data: they are no longer handler by the model. A hook "useSpecialData" has been created, and it allows fields (components) to fetch additional data they require. 2) The new model uses onchange2 [2]. With onchange2, we send and receive a diff, instead of the whole state of the record. Morever, onchange2 uses unity, which means that returned commands for x2manys (e.g. command 4, LINK) contain the values of the corresponding records, so we don't need to fetch them in a separate call afterwards. 3) The new model no longer triggers deep renderings (render(true)). It is instead based on fine-grained reactivity (i.e. only what depends on what has changed is re-rendered). We introduced a hook "observeRecord" which allows a component to subscribe itself to some keys in a record datapoint, and register a callback to execute when those keys change (e.g. to fetch data).
