[Mesa-dev] [PATCH] docs: Document and *require* usage of Signed-off-by

[Jordan Justen]

This adds the "Developer's Certificate of Origin 1.1" from the Linux
kernel. It indicates that by using Signed-off-by you are certifying
that your patch meets the DCO 1.1 guidelines.

It also changes Signed-off-by from being optional to being required.
