In Python 3, all of these were "consolidated" under urllib(.request,
.parse, .errors) which is inconvenient.
Since we already have hard dependencies on requests and
werkzeug(.urls, which is a backport of Python 3's unicode-aware
urllib.parse) migrate *everything* to that.
A sticking point is urllib2.URLError, those were (mostly) replaced by
the slightly more general IOError which URLError extends.
* cross-version metaclass spec
* more formally deprecate browse_record and browse_null since they
were using metaclasses anyway
* update docstrings referencing the latter
In Python 3:
* various builtins and dict methods were changed to return
view/iterable objects rather than lists
* and the separate Python 2 view/iterable builtins and methods were
removed altogether
This is problematic when using these items as list (which the happens
repeatedly in Odoo), but more viciously when iterating *multiple times*
over them (which also happens, which I've messed up multiple times while
writing this, and which is a pain to debug even when you've just created
the issue).
Convert all code using these to semantics-matching cross-version
helper functions to get the LCD behaviour between P2 and P3, and
forbid the builtins via lint.
issue #8530
Problem: the update of custom models/fields is not fully transactional, and may
potentially lead to an inconsistent database. An other problem is creating two
custom fields by writing on a model: if the second one fails, the first one has
been committed without notice. Retrying the request will give an unexpected
error (duplicate field name).
Solution: never commit in the middle of a request. If the changes have an
impact on the registry, then mark it as invalid (with a new flag), and signal
registry invalidation after everything has been committed. If the request
fails, reset the registry. Both registry and cache invalidation are handled
the same way.
Introspection attributes on function and methods were originally
prefixed with func_ or im_ e.g. im_class or func_name. For coherence with the
rest of the data model, Python 3 added dunder attributes (__func__,
__code__) and removed the old style, the dunder attributes were
backported to Python 2.6.
Use dunder attributes everywhere we're currently using func_* or im_*
attributes.

#8530
- As of v10, manifest files should be named `__manifest__.py`
- For backwards-compatibility, __openerp__.py manifest files
will still be supported for the time being
- Limited refactoring, to add support for the 2 different
naming conventions
- All textual references to __openerp_.py updated in
documentation and examples
