utils: Replace DEC copyright with Ran's
This is not something I do often, but I have good reason here ...
utils.h has been totally rewritten since import, and now contains no
original DEC content. Everything in here has been added by Ran, and I
do not believe that any lingering content from previous iterations is
substantial enough as to be copyrightable.
Replace DEC's copyright (and license with hostile advertising clause)
with Ran's boilerplate copyright and license statement.
