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.

fixup for 452e8f78

* [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

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 !1007 (comment 136801)

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

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.

Remote-User header is not managed by the frontend.

for https://github.com/grafana/loki/issues/3177

While investingating this, I realized loki officially supports golang 1.15, but
beside this, everything seems to work fine, so let's keep using 1.16

* version up
 * ssh keys support
 * mod_auth_web support
