More cleanup in udev rules:

Browse Source 
- add copyright notice for 10-dm.rules.in,

 - set DM_UDEV_DISABLE_{DISK, OTHER}_RULES_FLAG in 11-dm-lvm.rules directly
   for inappropriate and non-top-level subdevices in case we use older kernels
   where DM_COOKIE is not used (and therefore there are no flags passed from
   the LVM process itself). This applies for older kernels (version < 2.6.31),

 - remove unnecessary filters in 95-dm-notify.rules - the DM_COOKIE env var
   itself is set for change/remove udev events and for DM devices only so
   there's no need to double-check this.
