kirr/wendelin.core@t is current WC2 draft.

In 6e696faa "v↑ tempstorage 2.12.2 -> 5.2(ZODB5) 3-nxd(ZODB4-wc2)" we upgraded
tempstorage for ZODB5 and ZODB4-wc2, but were careful and left tempstorage,
that was being used with ZODB4, intact. However @tomo suggests that we should
also upgrade tempstorage for ZODB4 because of the loadBefore fixes and not to
further grow divergence in between ZODB4 and ZODB4-wc2:

    I understand that keeping the same version of tempstorage for ZODB 4 is to
    be on the safe side but I'd rather change it to tempstorage4-wc2 anyway. I mean
    we have a bugfix but we are afraid to apply it. Also, The less difference
    between ZODB 4 and ZODB 4-wc2 the better (everything will be more tested this way).

-> So let's do that.

tempstorage 2.12.2 is from 2012 and misses loadBefore fixes which are
important when ERP5 is run with ZODB5 or ZODB4-wc2:

https://github.com/zopefoundation/tempstorage/commit/d187a86d
https://github.com/zopefoundation/tempstorage/pull/16

When the first loadBefore fix is not there, the problem manifests itself as
Zope not starting correctly with the following error in its log:

    2021-07-02 08:37:25,579 ERROR Zope.ZODBMountPoint Failed to mount database. <class 'ZODB.POSException.ReadConflictError'> (^@^@^@^@^@^@^@^@)
    Traceback (most recent call last):
     File ".../eggs/Zope2-2.13.30-py2.7.egg/Products/ZODBMountPoint/MountedObject.py", line 248, in _getOrOpenObject
       root = conn.root()
     File ".../parts/ZODB4-wc2/src/ZODB/Connection.py", line 405, in root
       return RootConvenience(self.get(z64))
     File ".../parts/ZODB4-wc2/src/ZODB/Connection.py", line 276, in get
       p, serial = self._load(oid)
     File ".../parts/ZODB4-wc2/src/ZODB/Connection.py", line 246, in _load
       return self._loadFrom(oid, self._storage)
     File ".../parts/ZODB4-wc2/src/ZODB/Connection.py", line 255, in _loadFrom
       raise ReadConflictError(oid)
    ReadConflictError: ^@^@^@^@^@^@^@^@

When the second loadBefore fix is not there, the problem manifests
itself as data corruption and sporadic POSKeyErrors
(https://github.com/zopefoundation/tempstorage/issues/8).

-> Fix both problem by using recent tempstorage with ZODB5 and ZODB4:

- ZODB5: just use tempstorage 5.2 egg
- ZODB4-wc2: use tempstorage 3 + loadBefore backports:
  https://lab.nexedi.com/nexedi/tempstorage/commits/3-nxd
- ZODB4: stays at 2.12.2 for now for this change to be as risk-free as
  possible. However, due to the fixes and e.g. https://github.com/zopefoundation/tempstorage/issues/8#issuecomment-873894941
  it makes sense to switch ZODB4 to tempstorage 3-nxd as well.

/cc @tomo, @romain, @rafael

Also improve the recipe `switch-softwaretype' by catching the possible errors.

This is based on commit "Firefox Version Up to 78.1.0esr", but it does not
replace the default firefox, just enable a new version for now.

This is a "minimal" version up to fix https://bugs.gentoo.org/580392 which
appears now that we build with gbm

some components, like binary chromium needs libgbm, which is part of mesa, but
build only when enabled.

* [slapos-master](https://nexedijs.erp5.net/#/test_result_module/20210629-DE509CB3/23) is failing in checkSoftware step, because:
  * wcfs is linked against system zlib (fixed in this MR)
  * the .so in the build directory have missing references. I think we don't need to check in build folders and also liblibgolang is missing, but it's not a problem because of the way we load dynamically at runtime, so I suggest changing checkSoftware in nexedi/slapos.core!317
* [gitlab](https://nexedijs.erp5.net/#/test_result_module/20210629-DE509CB3/10) is failing for some time because mimemagic have been yanked from rubygems. This is a minimal change to get the test running again, to prevent other problems to sneak in while we don't have tests

see nexedi/gitlab-ce!5

On wendlin.core 2, wcfs uses github.com/DataDog/czlib which uses zlib. We also
need to instruct linker to set a rpath for slapos' zlib, otherwise the system
one will be used.

Suggested by Kirill on nexedi/slapos!1007 (comment 136801)

Change all `check_port_listening` promises to `check_socket_listening`
and rename all associated `config-hostname` arguments to `config-host`

It was broken since commit 92779bf4.

With recently backported fix for h5py

This software uses xml for parameters serialisation, so we can not use
boolean type. As a result, smtp_verify_ssl was always "true" and disabling ssl
verification was not working.

When accessing the smtp server from localhost, grafana attempt STARTLS and
verifies certificate, so scenarios of using localhost:25 as smtp server usually
needed smtp_verify_ssl="false".

Fixes and tests https://github.com/apache/trafficserver/issues/7880

By following:

https://docs.trafficserver.apache.org/en/9.0.x/release-notes/upgrading.en.html

configuration has been adapted.

Tests to new version string has been adapted with smaller fixes, including a
bit more time for log to appear in squid.log.

Previous patch is incorporated with 4f6bfe439e4ed7794992e16c16eb991976a3018e

The missing run was hidden by slow Caddy warmup procedure.
