This patch add support for new iswmd parameter passed to the kernel command line.
When this parameter is added to the command line it will change support for isw_raid_member format:
- isw_raid_member is removed from udevTypes for DMRAIDMember
- isw_raid_member is added to udevTypes for MDRAIDMember
- md_uuid will be read from udev database
New function md_is_isw() was added to check kernel command line parameter.
