This patch add activation of MD container and add disk to the container.
To make this possible name of devDir was changes to /dev/md.
Name of container is created as imsm[number].
Container path can be for example /dev/md/imsm0
Name of the native format array is changed from md[number] to [number] only.
Array path can be for example /dev/md/0
Function mdraid.mdadd_no_degraded is use only for adding first member to the array.
It is needed for isw format. For the next disks function md_array._addDevice is used in
other path.
