And upgrading to the python3-supported version (1.1) requires gtk3 and recent
versions of freetype, glib, atk, gtk, gtkmm, atkmm...

Besides of consistency, this also avoids zope eggs versions to be overriden elsewhere.

This reverts commit 27f574bc.

NEO now should support zodbpickle >= 2 with nexedi/neoppod!19.

Going Go1.16.10 -> Go1.16.13 brings in fixes to compiler, runtime and stdlib

Tested manually via adjusted helloworld because nothing intree currently uses Go1.16.

Without this we sometimes hit the socket path length limit when testing
ERP5 inside Theia inside erp5testnode.

wait a first time that ERP5 have finished processing activities for
initial site creation and tolerate that during this time zopes might

With ERP5 commit nexedi/erp5!1529
timerserver is started from wsgi startup script and the config in zope.conf
only applies to the medusa/ZServer mode.

Since ERP5 commit 8f3b77517e (Force use of the new TimerServer, 2019-09-13)
the timerserver egg is not longer used, so it's not needed to install
and configure it.

In ubuntu 21.04 (libc6 2.33-0ubuntu5) or current debian testing
(libc6 2.32-5) no longer use open to open /etc/hosts, but what appears
as "openat" in strace output - but can not be replaced by defining an
openat function.

This uses https://github.com/figiel/hosts which uses another approach
of replacing getaddrinfo, gethostbyname* and inet_aton.

Users have been updated a bit, because there are some small differences:
 - the /etc/hosts replacement file is defined by HOSTS_FILE environment
   variable, not HOSTS
 - the library name is libuserhosts.so, not userhosts.so

Other notable differences, for which we did not need code change are:
 - the new library also try to load a file when HOSTS_FILE is not set
 - the new library still use original /etc/hosts file
 - the new library supports aliases to hostnames, not only ip addresses
