Now that we're closer to switching to P3 for good, these helpers have
outlived their usefulness, and mostly add noise.
All remaining dict.iter*() or dict.view*() must be converted to the
normal keys(), values() or items() calls.
Whenever the result is likely to be used for more than the scope of a
loop, or when the dict needs to be modified during iteration, the calls
must be wrapped in a ``list()``, to protect the new P3 semantics.
Those cases are very exceptional.
Also removed some dead code or improved the API to remove unnecessary
conversions.

* StringIO removed from stdlib, replace with io
* try to correctly handle BytesIO/StringIO (one is for bytes the other
is for text)
* fix base64: Python 3 removed bytes-encoding and bytes-bytes
codecs (via #encode) so replace all calls to str.encode('base64'),
also b64encode is a bytes->bytes conversion so attempt to properly
handle that

* add Sphinx 1.6 compatibility (use app.set_translator when
available as in that case programmatically setting
html_translator_class is broken)
* fix a bunch of code block lexers to avoid warnings & get better
coloration
* add a few options which were referred to without being actually
defined
* fix some rST formatting

Also lint away verboten stdlib modules.

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.

* LDAP import: python-ldap is not python3-compatible, pyldap is
Warning: only supported from debian Stretch (current testing)?
https://packages.debian.org/search?searchon=names&keywords=pyldap
* implicitly relative imports
* imports of moved or removed stdlib modules

* Reverse wrapper courtesy of @rco-odoo's original P3 branch
* thin compat module stripped down from werkzeug (to augment as needed)

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

For readability and coherence, in Python 3 the prefix for octal
literal becomes ``0o`` (rather than just ``0``). This new version was
also added to Python 2 as of 2.6.
Convert all octal literals in file-manipulation code (POSIX ACL), and
fix a few integers which were unwittingly octal.

Redundant with `in` and removed from Python 3.
Removed odd, old and long-unused UpdatableDict (which defines and uses
has_key) and UpdatableStr (which was nearby and caught in the blast),
validated with al.
(lib2to3.fixes.fix_has_key)

* `<>` was removed and should be replaced by
`!=` (lib2to3.fixes.fix_ne)
* `\`` was removed and should be replaced by either `repr()` or the
`%r` format string modifier (lib2to3.fixes.fix_repr followed by
hand-rolled edition to replace concatenation)
