Adam Duskett 0f01b69885 package/python3: bump version to 3.9.6
Other changes:
  - Rename 0034-lib-crypt-uClibc-ng-doesn-t-set-errno-when-encryptio.patch to
    0035-lib-crypt-uClibc-ng-doesn-t-set-errno-when-encryptio.patch, as to not
    overlap with 0034-Add-an-option-to-disable-the-berkeleydb-module.patch

Subject: [PATCH] Add infrastructure to disable the build of certain extensions
Some of the extensions part of the Python core have dependencies on
external libraries (sqlite, tk, etc.) or are relatively big and not
necessarly always useful (CJK codecs for example). By extensions, we
mean part of Python modules that are written in C and therefore
compiled to binary code.
Therefore, we introduce a small infrastructure that allows to disable
some of those extensions. This can be done inside the configure.ac by
adding values to the DISABLED_EXTENSIONS variable (which is a
word-separated list of extensions).
The implementation works as follow :
* configure.ac defines a DISABLED_EXTENSIONS variable, which is
substituted (so that when Makefile.pre is generated from
Makefile.pre.in, the value of the variable is substituted). For
now, this DISABLED_EXTENSIONS variable is empty, later patches will
use it.
* Makefile.pre.in passes the DISABLED_EXTENSIONS value down to the
variables passed in the environment when calling the setup.py
script that actually builds and installs those extensions.
* setup.py is modified so that the existing "disabled_module_list" is
filled with those pre-disabled extensions listed in
DISABLED_EXTENSIONS.
Patch ported to python2.7 by Maxime Ripard <ripard@archos.com>, and
then extended by Thomas Petazzoni
<thomas.petazzoni@free-electrons.com>.
