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 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 0cf70a6e was necessary.
However in neoppod!18 and
neoppod!21 a common
URI format for NEOgo and NEOpy was agreed on. Therefore most changes of
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 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 wendelin.core@63153845...db6fea3d
for complete list of changes.
