- add or fix decorators on methods - fix most compute methods (wrong dependencies) - revert changes in `eval_context` of `ir.actions` - various code simplifications and improvements - migrate methods that were not - ir_qweb: modify `QWebContext` to take an environment instead of `cr`, `uid`, `context` - ir_qweb: convert `AssetsBundle` to use new API `env` - ir_ui_view: use decorator `multi` on method `read_combined` - ir_ui_view: ensure that method `render` is never called with an xml_id - ir_ui_view: factor out part of the `ormcache` key of method `_read_template`
