This patch updates copyright.el to auto-insert SPDX- declarations. There
is one new user-facing command 'copyright-spdx' and a few new
customizable variables.

It also makes the 'copyright' command use 'comment-add' so that the
comment marker ;; is correct in Lisp modes, for both the SPDX and
default formats.

While working on this I also noticed the copyright skeletons in
autoinsert.el are inconsistent - they have an extra space relative to
those of copyright.el. IMO autoinsert.el should be adjusted to use the
copyright.el code instead of reimplementing it.
