    Fix two more SIZE_T_CEILING issues
    
    This patch imposes (very long) limits on the length of a line in a
    directory document, and on the length of a certificate.  I don't
    think it should actually be possible to overrun these remotely,
    since we already impose a maximum size on any directory object we're
    downloading, but a little defensive programming never hurt anybody.
    
    Roger emailed me that doorss reported these on IRC, but nobody seems
    to have put them on the bugtracker.
