- 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`
The `unittest2` package is simply a backport of `unittest` from the
Standard Library of Python 2.7 to previous versions.
There is no reason to use it any longer.
Closes#6941
