The pyeval name is quite confusing, given that there is already an eval
and an evaluate function in py.js, and that the web.pyeval exports two
evaluate functions.

Since this file is more about odoo specific customization to py.js, it
is renamed in py_utils to better express its intended use.

The parentedMixin doesn't automatically set the parent, so when this mixin
is used, the parent must be set manually. This wasn't done at several places,
and thus those elements weren't destroyed with their actual parent.

In master, we should probably make the ParentedMixin set the parent itself.

Fix a bunch of ill-documented/incomplete/incorrect method docs
Without this, the automatic doc generation does not work.

This commit tries to refactore the management of contexts and domains
in the webclient.

- Get rid of CompoundDomain: use standard array manipulation to
join multiple domains or use the Domain class (to be improved)
- Get rid of data.js build_domain and build_context methods
- Link this.record to the data point from the basic model for all
fields (not only relational fields)
- Add a getContext and a getDomain function to the basic model
data point (localData element) so that AbstractField implementations
can use them thanks to their this.record element.
- Remove the autocontext binding for field RPCs (see FieldManagerMixin)

Use this.rpc instead of Model object, with web.ajax if necessary.

nb: EventDispatcherMixin include now the custom_events managment instead
of widget
