Documentation/SubmittingPatches: Reference external DCO

The new developer-certificate-of-origin text is copied directly from
developercertificate.org [1] into a stand-alone file to avoid
confusion with the separately-licensed supporting text in
SubmittingPatches (following the example of stand-alone license files
like COPYING).  SubmittingPatches now references that file when
explaining the significance of Signed-off-by tags.

My changes to SubmittingPatches are licensed under both the Creative
Commons CC0 1.0 Universal license (see the `license` branch for full
text) and the GPLv2-linux (see the `copying` branch for full text), as
are my previous contributions to SubmittingPatches.  Pick whichever
one works best for you.

 introduced by the Linux kernel.  The sign-off is a simple line at the
 end of the explanation for the patch, which certifies that you wrote
 it or otherwise have the right to pass it on as an open-source patch.
-The rules are pretty simple: if you can certify the below:
-
-  Developer's Certificate of Origin 1.1

-  By making a contribution to this project, I certify that:
-
-  (a) The contribution was created in whole or in part by me and I

-  (b) The contribution is based upon previous work that, to the best

-      license and I have the right under that license to submit that
-      work with modifications, whether created in whole or in part
-      by me, under the same open source license (unless I am
-      permitted to submit under a different license), as indicated

-  (c) The contribution was provided directly to me by some other
