The version numbers based on the 15 years old N tag are confusing and
don't offer a lot of information about what release the version is close
to.

This patch stops using the N tag and always bases it on the most recent
dev tag instead. So instead of

N-78885-g966eade

One now gets

n3.1-dev-422-g966eade

Which offers a lot more informational value to users and developers.
