    Bug 22084: XFS server crash with many dropped connections
    
    http://bugs.freedesktop.org/show_bug.cgi?id=22084
    
    Fixes three crashes I hit investigating this report:
    
    1) Replace ffs() with a version that handles fd_mask sized arguments instead
    of int sized ones, so we don't get stuck in 64-bit builds when fd bits
    are set past the 32-bit boundary.  (os/WaitFor.c in the X server already does
    this.)
    
    2) Check that the client OsPrivate isn't already NULL before dismantling it
    in CloseDownConnection()
    
    3) Make sure we aren't overflowing the pClientsReady buffer when returning
    the list of clients ready for processing.
