In order to implement a proper versioning scheme, let's generate a version.h file that defines VERSION variable built from git workspace. The version format will be v<MAJOR>.<MINOR>-<COMMIT##>-<SHA1> Where: * MAJOR and MINOR are from the most recent tag * COMMIT## is the number of commits since last tag, to ensure incremental numbering * SHA1 is an abbreviated representation of the actual commit SHA. This requires building from a git workspace, with we are effectively calling 'git describe' during the build. We then define print_version() utility function to be used by all programs. Ensure that util.c depends on version.h and that we only update version.h timestamps when the version actually changes to avoid unnecessary rebuilds.
