Proper copyright headers

[ottok]

This is not urgent, but I'm filing this as a reminder that it would be good practice to have in each and every source file simple copyright and license headers.

See file http://labs.seravo.fi/~otto/galera-repo/logs/copyright. It is the output from the command
'licensecheck --copyright -r . -c .'

This issue is still valid. An excerpt from the licensecheck output:

I reported this in 2014. Maybe you @temeo want to fix this some time in 2021? :)
