Regenerate monitor password files if they are deleted.

This reverts commit 0fad9a6d.

Use md5sum to check if what we download is what we actually got.

GTK tried to compile against libcups when it was present in the system.
This failed the compilation if the includes were not present.

This commit sets "file" as the only backend for printing, thus
explicitly removing cups as a dependency.

See merge request !1649

Always install cups in lib folder, even when lib64 would be used by
default.

The multiarch strings (GNU target triplets) used currently for platform
detection are different in Suse, as they include the "vendor" ("suse" or
"pc" depending on the GCC version) and the OS part is just "linux"
instead of "linux-gnu".

This changes platform detection to use the constants available in
buildout for detecting the operating system and the `platform` module
for detecting the machine, instead of these multiarch strings.

Several components use patches directly from Github.
Unfortunately, Github changes the number of characters displayed for the
commits in index lines depending on the size of the repository.
That means, that the content of these patches may change, invalidating
the MD5.

By using the `?full_index=1` param
(https://github.com/orgs/community/discussions/46034#discussioncomment-4846112)
we can request that these patches include the full names of the commits,
thus preventing future changes.

if libnsl was installed on the system, openvpn would link with it
so be proactive and always link with slapos libnsl.

This patch from PR 147 wa a left over from development, when we merged
we used AccessControl 7.0 which included this patch.

 * https://github.com/mroonga/mroonga/commit/f4d3e6a612d346f690bbf68893e339ff0b69e5b8 might fix the crash we were observing with https://lab.nexedi.com/nexedi/slapos/-/blob/0fad9a6dcaf6f5750c03dcd2a6b42364207767ff/software/erp5/test/test/benchmarks.py , I ran this test 10 times without crash.

 * ~~There's a test failure in ERP5, but it does not seem harmful and we can have a workaround ( nexedi/erp5!1993 )~~ In the end, the problem was fixed upstream so we backport the fix.

Since upgrading to zc.buildout = 3.0.1+slapos004, slapos.rebootstrap
and slapos.recipe.template tests are failing due to: these two tests
running buildout, buildout installing develop eggs, develop eggs now
being installed with pip install -e instead of setup.py develop, and
pip install -e launching sys.executable -E at some point. This fails
because the tests are run using gpython:main script, which currently
does not support -E option.

As a quick fix run these two tests with a barebone python executable
and use export PYTHONPATH to provide the needed eggs. This is not as
good as gpython:main because PYTHONPATH will be inherited by all sub
processes and not just those launched with sys.executable, including
potentially other versions of python.

Old GCC versions wrongly patched `__has_include` directives in system
includes (using fixincludes).
This was reported in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91085,
and patches to fix this behavior are given in
https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=6bf383c37e6131a8e247e8a0997d55d65c830b6d
and are applied upstream in versions above 12.1.
This commit applies these patches to older GCC versions.

This bug in GCC's fixincludes manifest itself with several seemingly
unrelated symptoms.
In particular, there are two conflicting "mount.h" includes, one coming
from Linux and other from Glibc.
Newer Glibc included some preprocessor tricks to detect if the Linux
header has been previously included and prevent incompatibilities by not
redefining common symbols, thus allowing its header to be included
*after* the Linux header.
In case that the header is included *before* the Linux header, it uses
the aforementioned `__has_include` directive to detect and include the
Linux header before itself if present, thus preventing its inclusion
afterwards.
However, due to the `fixincludes` wrong substitution, the check was
always false, and thus including the Glibc header before the Linux one
caused the compilation to fail, with an error similar to:

This error was originally detected in Nexedi in
nexedi/slapos@fe60394b (comment 189391)
by @vpelletier, but no action was taken at the time to solve it.
Some of its symptoms were detected and fixed individually in
nexedi/slapos!1579 and
nexedi/slapos!1580 ,
by reordering the includes, but the above error in libmount, which could
not be solved that easily, made me delve more into the problem and find
the root cause.
