After the Odoo package is built, the package.py script uses a Docker
image to test the package. After that python3-qrcode was added as a
dependency for the package in 2ff49c5f , it revealed some issues.

A missing cli parameter and a forgotten '&&' in the Dockerfile prevented
the installation of the depending packages.

Also, the script shebang was wrong by launching python2.

Finally, the fact that python3-xlwt is missing in Debian stretch was
highlighted. With this commit, the python3-xlwt is explicitly removed
from the dependencies and the documentation is updated accordingly.

PKG-INFO is generated during the setup phase and is not needed anymore.
Also this file contains outdated informations.

py2exe is not used anymore to build the windows installer.

Commit cf853a78 removed all yml tests
and the yml import engine from Odoo forever, however PyYAML remains a
dependency even though it's not used anymore.

This commit removes any reference to this lib that could be found.

Since 2f7c03d9 the admin user could have any uid and the uid 1 is
reserved for the system user. As the uid was hardcoded as 1 when testing
packages, the tests were failing.

With this commit, the uid of the admin user is searched before testing
the packages.

Closes #26603

Since bf3193ac libsass is needed but is named libsass0 in Debian.
With this commit, the docker source image used for tests will build again.

Since 565277ac sassc is used as a
fallback when the python libsass is not available.

With this commit, the saasc package dependency is added to the rpm to
avoid installing libsass with pip.

Since 285ead28, `base` should be loaded
as a server wide module to enable rpc routes.

When the virtual machine used to build MS Win package takes too much
time (to build or to test the build), a warning is logged and the VM is killed.

Before this commit, the PID of the process was passed as an argument to
the warning method, causing a traceback.

When building the Windows installer, a virtual machine is used with
prepackaged python modules.

With this commit, the packaging script will try to install on the
virtual machine the python packages specified in requirements.txt.
Each package is installed individually, that way, if an install fails,
the install of the other packages continues.
At the end of the process, successfully packages are listed so that they
will appear in the build log files.

Also, the Makefile was cleaned in this commit (removal of py2exe stuffs).

A dependency to libsass was added in debian package and in the docker
file. The Odoo nightly builds of the deb package was failing because
this lib is named libsass0 in Debian.

Finally, this dependency is not required because python3-libsass already depends on libsass0.

Include libsass instead of node-less

Thank you to @d-fence for testing this.

As the windows package provides odoo from sources alongs with
python 3, the test of the build was failing.
The odoo-bin.exe was not found because py2exe is not used anymore.

Windows firewall is now disabled from package.py to prevent it
from blocking local xmlrpc calls.

Also, the docker containers were removed when package tests were
finished, even when no docker was involved in the process (e.g. only
a windows build).

This commit fixes the test part of the windows build process.

Nsis installer was installing the wrong MS Visual C++ redistributable
file. Python 3.6 needs MS Visual C++ 2015 redistruibutable files.

Also, Nsis now differentiate Windows architecture for the nssm service
and the MS C++ redist.

The automated tests of rpm,deb and src packages are using docker
images and containers. Those tests were not working as expected due
to various small glitches:
* some debian python- packages were missing in the Debian image
* pip was called instead of pip3 for the src test
* a wrong addons path was given for the tests
* the containers id's were wrong due to a bytes implicitly converted
  to str

Purpose: openid is not used anymore in Odoo, therefore it can be
safely removed.

Use python 3.5
Refer to correct page of the doc
Remove old bazar to git (was intended for the 8.0)

Remove outdated setup_dev script: it was intended for odoo developers but if you
are not able to make a git clone, you are going to have a bad time later.

Not that we really care about compileall, but some people apparently
do.

Closes #19849

Purpose:
    The psycogreen module is unmaintained. Last source update was in
    2015 and last pypi package was in 2012. Odoo only use a small
    part of the psycogreen module that could be written directly in
    the odoo code. This commit reproduce the small function from
    psycogreen used in ODoo and remove all depencies from it.
    Also the copyright and license are honored and the documentation
    is updated accordingly.

    bitbucket repos: https://bitbucket.org/dvarrazzo/psycogreen/

Purpose: When uninstalling using the windows uninstaller, python and
nssm were left beyond. This fix removes the python and nssm dirs also.

Purpose: When installing postgresql under windows, the '+' character is
unallowed. This was creating a bug when using the windows installer the enterprise
version which derivate the install path from the version number.

Windows can be slower to start than that, sometimes.

Purpose: for multiple reasons (bytecode change in python 3.6,
         missing files for some packages, py2exe is unmaintained
         ...) the py2exe solution cannot be used anymore.
         Odoo for windows will now use a portable Python that
         will be shipped with the Windows installer.
         For that purpose, a Winpython 3.6.2 is used.
         In order to build the Windows installer, a Winpython dir
         with all the Odoo requirements fullfilled, must exists on
         the build system (qemu-kvm VM).

* nsis installer:
    - Only the python dir is used to avoid packaging too much stuffs
    - better compression level
    - starts the Odoo service using nssm
    -  bump to V11
* change the default win10 build vm path
* print a warning when uncomplete addon move
* try to force remove of addon path:
  when the addons are moved to Odoo/addons, it happens that the
  destination already exists. In that case, the source addon was not
  deleted, resulting in a uneeded file duplication.
* fix version string to avoid invalid chars in windows service
* Add requirements adpated for WinPython
* package.py now shows the traceback when a build fails
* verify that a file exists before publishing
* debuild now creates an .xz file instead of .gz
* package: use logging module
* kvm CPU that works with older versions.
* fix a pexpect encoding bug
* fix the version to remove special chars '~' which is not appreciated
  by windows services

[REM] win32setup: Remove win32 python service

Purpose:
    Before this commit, the win32 service was managed by an executable
    builded from those two files with the help of py2xe.
    The win32 service is now managed by nssm which starts Odoo and therefore, those
    files are not needed anymore.

* Add an option to avoid signing deb package
* update windows vm name
* add memory to kvm as win10 needs 1G
* increase win VM timeout because win10 seems slower to start
* add an option to keep build dir for debugging purpose

Deprecates the previous pkg_resources-style packages. Our use was
not entirely spec compliant, and it broke with setuptools 31.
More information in https://github.com/odoo/odoo/pull/15718

Instead, use the pkgutil-style namespace packages.
This is spec compliant as long as all other distributions providing
odoo.addons use PEP 420 namespace packages (i.e. no __init__.py).
So this mechanism fully works on Python 3 only, but does not break
anything on Python 2.

Complements 021de21e and #16918

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.
