Do not remove the .info generated by lcov

Properly convert the data into a number of seconds by using duration_cast

The logger writes to std::clog

The config module doesn’t use the logger at all

Use an other implementation of a null_stream for the logger

e2e: remove the log_message step, because it causes race conditions

After printing the message, it calls “call_soon(run_scenario)”, and
sometimes, if a stanza handler has already been queued, then that handler
will be called BEFORE the “run_scenario” function could be run, and so no
stanza_checker had the possibility to be set.

Don’t use global static members but functions that return a reference to an internal static object

See https://github.com/randombit/botan/issues/761

Init some members of TcpClientSocketHandler

Fix the locales in the docker test images

In time.cpp, use the en_US.UTF-8 locale, instead of en_US.utf-8

(which apparently doesn’t work on freebsd)

Use a portable way to get the relative paths into __FILENAME__

ci: Print the locals before running

ci: Remove openbsd job for now

[skip ci]

CI: refactor, and enable some specific test only on the master project

Because some of the jobs (the one using ssh runners, freebsd and openbsd)
use runners that are only available on my own project and not forks (for
security reasons), and some other jobs (coverity and sonar-qube) use private
variables to be able to run.  So, all these jobs would fail if run on a fork
project.

Add some missing includes

Force the freebsd build to use clang++

ci: Don’t display g++ and clang++ --version

ci: don’t set the locale env variablesx

Add a freebsd ci test

e2e: Accept even more unordered things in the connection sequence
