- Fix a file leak issue when mdadm is in monitor mode

- Update mdadm init script so that status will always run and so return
    codes are standards compliant
- Fix assembly of version 1 superblock devices
- Make the attempt to create an already running device have a clearer error
    message
- Allow the creation of a degraded raid4 array like we allow for raid5
- Make mdadm actually pay attention to raid4 devices when in monitor mode
- Make the mdmonitor script use daemon() correctly
- Fix a bug where manage mode would not add disks correctly under certain
    conditions
- Resolves: bz244582, bz242688, bz230207, bz169596, bz171862, bz171938
- Resolves: bz174642, bz224272, bz186524
