Fixup of a3e15fc4.

Before this patch SlapOS users had to manually add SSL files in case WCFS
was used in combination with NEO+SSL. This is bad as we can easily forget
to update local parameter files when updating instance parameters ("_ca",
"_cert" and "_key"). This builds up on nexedi/slapos@706801f2.

NEO/go doesn't understand what it should do with these parameters and
raises an error in case they are added to the NEO URI [1].

'wendelin.core' needs to differentiate between a NEO cluster with SSL
and without SSL from a normalized zurl (e.g. a zurl which doesn't
contain any paths to encryption files). Therefore the 'neo' / 'neos'
scheme difference was introduced in nexedi/neoppod@bc3e38ea.
This patch introduces this difference in zurl that SlapOS provides for
'wendelin.core' - this essentially fixes a ERP5+WCFS setup that connects
to a NEO cluster with activated SSL.

We only need one query identifier ('?'), while query options should be
separated by the separator identifier ('&'). This essentially changes
the resulting NEO URI from

  neo://cluster@IP&a=b?b=c

to

  neo://cluster@IP?a=b&b=c

This reverts commit 0cf70a6e.

NEOgo and NEOpy diverged wrt the NEO URI format. Due to NEOgo
changes in the NEO URI format nexedi/slapos@0cf70a6e was necessary.
However in nexedi/neoppod!18 and
nexedi/neoppod!21 a common
URI format for NEOgo and NEOpy was agreed on. Therefore most changes of
nexedi/slapos@0cf70a6e are no
longer necessary. We still need the difference between 'neo' (without
SSL) and 'neos' (with SSL), but we'll re-introduce this in the next
commit.

This revert keeps the changes made in nexedi/slapos@6fa1d9ae as this is still
needed.

New 'wendelin.core' version contains several bugfixes that were
discovered in field usage. Furthermore it introduces the new 'ZBlk_fmt'
option 'auto' that heuristically sets ZBlkfmt to gain a good ratio between
read time and database size, improves python3 compatibility and synchronizes
NEO zurl scheme between NEO/py and NEO/go.

See nexedi/wendelin.core@63153845...db6fea3d
for complete list of changes.

don't test it in python2 anymore

it seems the RPC deleteToken never returned NOT_FOUND anyway.

we are not using this command line utility, in erp5 tests (
product/ERP5Type/tests/Python3StyleTest.py ) we are using the python
API directly, not the command line.

if developer needs to invoke 2to3 it is present in ${python:location}/bin/

Also, md5sum option has been renamed runtime_plc_md5sum.

This is a fixup of 7df1d5fe.

this does not work when serving the raw blob on gitlab, so it is not
always usable for parameter editor.

The ISO used is a modified version of the Online version (no
repositories bundled in the CD) with updates
(SLE-15-SP6-Online-x86_64-QU1-Media1.iso) available in
https://www.suse.com/download/sles .

The only modification done is to set the "timeout" variable in
/boot/x86_64/loader/isolinux.cfg to 0, so that the KVM does not
automatically boot from disk after a timeout if the user does not press
a key (which was a problem that we found while testing this distro that
made difficult to install it).

See merge request nexedi/slapos!1655

And revert "software/slapos-testing: Quickfix python -E errors" now
that pygolang's pymain supports -E option.

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 nexedi/slapos!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.
