* walksymlinks is useless, os.walk got followlinks in 2.6
* tempdir is redundant with tempfile.TemporaryDirectory added in 3.2
* listdir(recursive=False) is just os.listdir (I guess recursive=True
is somewhat useful)
* zip_dir is *not* redundant with shutil.make_archive:
- zip_dir handles the archived root differently
- zip_dir sorts files, make_archive sorts directories
- make_archive explicitly adds entries for directories (including
empty), sorts directories, doesn't sort files; zip_dir sorts
files (including with a custom key function) but ignores directories
- zip_dir filters out a bunch of trash files

Signed-off-by: Christophe Simonis <chs@odoo.com>
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.
