[PATCH] introduce OPTIONS=ignore_device, ignore_remove, all_partitions" key

Here we move all possible options into a own key to make it possible
to have options-only rules.

The options on the NAME key are removed from the man page and will
be removed from a future version of udev.

For ignore rules, OPTIONS="ignore" should be used.

The rule:
  SUBSYSTEM="block", SYSFS{removable}="1", OPTIONS="all_partitions"

will create all partitions for a block device which is known to have
removable media (a check for cdrom drives would be needed too).
