version/spec: init
This is the second step in a repo-wide versioning system after the new
build status generator.
It introduces a proto representation of the essential version data which
is attached to artifacts generated from this repository.
The definition encompasses an informal spec on how this data can be
serialized to a SemVer 2.0.0 version string, which will be used in human
readable output and with interoperability with external systems.
