Add default udev rules. Update dm-ioctl.h comments.

# Udev rules for device-mapper devices.
#
# These rules create symlinks in /dev/disk directory.
# Symlinks that depend on probing filesystem type,
# label and uuid are created only if the device is not
# suspended.
Use udev flags in the rules and cleanup the rules: - remove default permissions set in 95-dm-notify.rules (and add a hint in 12-dm-permissions.rules to set it by the user directly) - add multipath DM_ACTION=="PATH_FAILED" filter - remove unnecessary filters in the headers of the rules (we can simply use DM_UDEV_RULES_VSN instead) - fix symlink priorities in /dev/disk/ (snapshot volumes have low priority for FS UUID symlinks so it will not overwrite symlinks for the origin)

# "add" event is processed on coldplug only!
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.

Several changes in udev rules: - add DM_UDEV_RULES_VSN to provide a variable to be checked for in the other rules (e.g. to check that DM rules are actually installed, we can alternate functionality in the other rules based on this information, also we have versioning support for the rules) - set proper sbin path for dmsetup and blkid, /sbin first, then /usr/sbin. This is necessary for anaconda to work properly. - add 'last_rule' for cryptsetup's temporary devices (symlinks in /dev/mapper only)
