    scripts/oe-build-perf-report: show recipe version changes in html report
    
    If buildstats are available (for a certain measurement), show recipe
    version changes between the two builds that are being compared. The
    information shown includes new and dropped recipes as well as changes in
    recipe version, revision or epoch.
