break out version.go into a package

[paultag]

It'd be great to break out version.go into a package, so other debian go tooling can use it.

This would be helpful for the following 2 things (at least) that I want:

• gbp import-orig update workflow (based on XS-Golang-Import-Path and version.go to create a new tarball, import-orig and dch)
• uscan-alike (or uscan patch?) to check when we're out of date (not a huge deal, but good to know)

I'm cool with importing dh-make-golang, or if you want a new common repo for this stuff, that would be great as well

SGTM. Do you want to send a pull request?

A friend of mine wants to work on a uscan patch for this, but it’ll take him at least one more month until he can get started. Do you have a particular feeling of urgency about it?
