Formalize the meaning of Signed-off-by

Up to now Signed-off-by was not formalized so I doubt it has had any
significance. This patch makes the Linux Kernel's rules explicit (by
borrowing even the wording from it).

+PTXdist development
+===================
+
+Development Tree
+----------------
+
+PTXdist uses git for version control. The master repository is available at
+
+	git://git.pengutronix.de/git/ptxdist.git
+
+Patch Guideline
+---------------
+
+Patches for PTXdist are always welcome. If you created a patch, send it to
+ptxdist@pengutronix.de for review. Each patch accepted into the master
+repository must be certified to be compatible with PTXdist's license (GPL v2,
+see COPYING). To do this you have to sign your patches (or the ones you apply
+and/or forward). 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
+            have the right to submit it under the open source license
+            indicated in the file; or
+
+        (b) The contribution is based upon previous work that, to the best
+            of my knowledge, is covered under an appropriate open source
+            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
+            in the file; or
+
+        (c) The contribution was provided directly to me by some other
+            person who certified (a), (b) or (c) and I have not modified
+            it.
+
+        (d) I understand and agree that this project and the contribution
+            are public and that a record of the contribution (including all
+            personal information I submit with it, including my sign-off) is
+            maintained indefinitely and may be redistributed consistent with
+            this project or the open source license(s) involved.
+
+then you just add a line saying
+
+        Signed-off-by: Random J Developer <random@developer.example.org>
+
+using your real name (sorry, no pseudonyms or anonymous contributions.) at the
+end of the patch description.
+
+There are some more usual tags (like Acked-by or Reported-by) which only have
+informational character and so are not formally specified here. See the Linux
+kernel (file: Documentation/SubmittingPatches) for how they are used here, too.
