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inferred from git blame, and is often outdated.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.

 This directory contains ethernet-based drivers for fronthaul. The only functional versions today are ECPRI time-domain (split 8) over UDP for AW2S and IF4.5 (split 7) for OAI RU over UDP. The RAW ethernet implementation is currently not tested and quite possibly obsolete.

 # Top-level
 
 The files implement the OAI IF device interface which provides the transmit/receive (trx) functions for generic ethernet-based devices. Some minimal control-plane socket handling for IF4p5 is also provided. It comprises the following top-level functions (ethernet_lib.c) which are mapped to the OAI device structure:
