version: automate and cleanup ver handling

Create a single function to return the version string, to avoid lots
of ifdefs in multiple places.

Make the version determine the 'release' status. If the version from
autoconf has '-dev' in the name, it is not a release. If it hasn't
it is considered a release version.
