    Deprecate g_unix_mount_monitor_set_rate_limit()
    
    Deprecate g_unix_mount_monitor_set_rate_limit() and turn it into a
    no-op.
    
    This function doesn't behave as advertised.  It only controls rate
    limiting for filesystem-based monitors.  It has no impact over reporting
    mount changes on Linux, for example, because those are based on polling
    for changes in /proc (which doesn't use filesystem monitors).  It also
    has no impact on Mac OS because a library interface is used there.
    
    This was added in https://bugzilla.gnome.org/show_bug.cgi?id=521946 in
    order to be used by HAL, which is effectively dead.  udisks no longer
    uses this code at all.
