dev-tools: Added script for updating copyright years in files

Very simple tool which modifies the Copyright lines in all git checked-in
files with an updated year.  Lines only listing a single year (2016) will
be modified to list a range instead.

Only the Copyright lines owners of specific owners will be modified.  The
script will need to be slightly updated to cover more owners.  See the
UPDATE_COPYRIGHT_LINES line in the script for the currently set owners.

v2 - On-the-fly-commit-update: use vendor/ instead of cmocka and
     add @sophos.com to the list of copyright holders to update
