This commit replaces calls to pycompat helpers that were intended for
python 2 <-> python 3 interoperability for python 3 builtins, as python
2 is no longer officially supported by Odoo.
This includes:
* calls to imap/izip/ifilter replaced by map/zip/filter
* uses of text_type replaced by str
* uses of unichr replaced by chr
* calls to implements_to_string, implements_iterator removed
* string_types and integer_types replaced by str, int respectively
* calls to to_native replaced by calls to to_text
This is done in preparation to the removal of these deprecated helpers
in the following commit.

Closes #20391

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

In Python 3, ``print`` becomes a builtin function. This is available
in Python 2 by importing the ``print_function`` feature from
``__future__``, the feature is conveniently still available in Python
3 (it just does nothing).

Demoted to library in Python 3, see if uses can be replaced by more
specific construct, just import functools.reduce otherwise.
