Support udev flags even when udev_sync is disabled or not compiled in.
This provides better support for environments where udev rules are installed
but udev_sync is not compiled in (however, using udev_sync is highly
recommended). It also provides consistent and expected functionality even
when '--noudevsync' option is used.
There is still requirement for kernel >= 2.6.31 for the flags to work though
(it uses DM cookies to pass the flags into the kernel and set them in udev
event environment that we can read in udev rules).

More cleanup in udev rules:
- 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.

Remove 'last_rule' from udev rules.
'last_rule' option has been removed from udev (version >= 147).
From now on, we require foreign rules to check and honor
ENV{DM_UDEV_DISABLE_OTHER_RULES_FLAG} instead. Foreign
rules should be skipped totally when this flag is set.
