classes/seppuku.bbclass: Add a class which might report build issues to a bugzilla directly

    Start adding seppuku. It listens to TaskFailed and NoProvider failures
    logs into a bugzilla and calls empty stubs to find a bug report.
    We use the urllib2 and cookielib from python2.4 to handle the session
    cookie for us automatically. This library is sadly not present in python2.3
    but it eases my life.
    The old BugZilla installed at OpenMoko has no support for listing the
    bug report as csv or xml file, this will force me to parse the HTML which
    I will do for now. This assumes that only one bug report with the exact
    name can exist.
