Remove most doxygen file-level commands, copyrights, and authors

Remove the \file directive, as it is always superfluous  because the
current file is implicit [1]:

> If the file name is omitted (i.e. the line after \file is left blank)
> then the documentation block that contains the \file command will belong
> to the file it is located in.

Author names and e-mails are not relevant for us: it can always be
inferred from git blame, and is often outdated.

Eurecom code has been contributed and was under OAI PL v1.0/v1.1.

For the cpack package contact: put generic email address that is
independent of an individual and that will remain reachable.
