Update COPYING with GPLv2 with new FSF address

The mailing address of FSF changed quite a while ago.  Also the expansion
of the acronym LGPL (which we don't use) is "Lesser GPL" not "Library GPL"
these days in recent copies of GPLv2.  Update the copy we have with a
fresh download of <http://www.gnu.org/licenses/gpl-2.0.txt>.

This incidentally removes form-feeds in the text we retained for all these
years.

Add a COPYING notice, making it explicit that the license is GPLv2.

Let's bite the v3 bullet when it comes, although if people want to,
they can just state "or later at discretion of Linus" in their copyright
messages.

SubmittingPatches: adjust content to be project-agnostic

Remove kernel-specific stuff (e.g. maintainers, emailed-patches) and
consolidate things that were treated differently in the kernel and git
versions (e.g. pseudonyms).

The slight-modification paragraph is mostly unchanged.  I just removed
the branch/subsystem maintainer leader and re-wrapped the paragraph.

SubmittingPatches: replace tabs with spaces and normalize DCO indent

I replaced each tab with two spaces.  No need for excessive 8-space
indents.

remove doubled words, e.g., s/to to/to/, and fix related typos

I found that some doubled words had snuck back into projects from which
I'd already removed them, so now there's a "syntax-check" makefile rule in
gnulib to help prevent recurrence.

Running the command below spotted a few in git, too:

  git ls-files | xargs perl -0777 -n \
    -e 'while (/\b(then?|[iao]n|i[fst]|but|f?or|at|and|[dt])\s+\1\b/gims)' \
    -e '{$n=($` =~ tr/\n/\n/ + 1); ($v=$&)=~s/\n/\\n/g;' \
    -e 'print "$ARGV:$n:$v\n"}'

Update DCO ("signoff") rules to 1.1

This adds a clause that notes explicitly that the person doing the
sign-off knows that the project (and his sign-off) is public and will
possibly get archived and re-distributed.

Start documenting the sign-off procedure in SubmittingPatches

We already have over 200 sign-off lines in the kernel, so
let's document the thing, even if discussion may still be
on-going.
