This changes all "Name Surname for CERN" to "Copyright CERN, author
Name Surname".  This is trivial and makes no change, with a few
expections:

- all trivial Makefiles that had "for CERN" lines have now no
attributions, as they are trivial anyways.

- a few unrepresented files have not the copyright notice (especially
ptpdump, that I wrote in 2012).

- a few "for CERN" remain in subprojects, where I didn't touch anyrhing

This simple tool requests a time adjustment, specified in seconds
expressed as a floating point values ("0.001", "-.2", "-4" ...).

It can be used to force time differences between hosts while checking
how ppsi (or other time daemons) work.
