    ptserver: Return error when exceeding _MAXPRLIST
    
    Currently, if the ptserver tries to reply to a client with a 'prlist'
    longer than OPENAFS_MAXPRLIST, the call will abort with
    RXGEN_SS_MARSHAL (for e.g., PR_GetCPS, PR_ListElements). This is a
    rather confusing error code for the peer, since the peer hasn't done
    anything wrong, and the error code looks like a networking error since
    it's negative.
    
    We can easily avoid this if we just check to see if we are exceeding
    the OPENAFS_MAXPRLIST limit, and return a clearer error code. So,
    return PRTOOMANY when we extend a 'prlist' to longer than
    OPENAFS_MAXPRLIST.
    
    Actually hitting the OPENAFS_MAXPRLIST limit is generally unlikely,
    but can be very confusing when it happens. Also log a message in this
    situation, to try and help explain what's going on.
