imp 4a902ab86d Remove 'All Rights Reserved.' from all of my Copyrights in sys/arm and
always use 'M. Warner Losh' for consistency.

'All Rights Reserved.' was prescribed by the Buenos Aires Copyright
Convention of 1910, but has been mostly dead since the early 1990's
and completely meaningless since 2000 when Nicaragua ratified the
Berne convention.

Some files not done due to ambiguity of various types.
