dm raid: introduce extended superblock and new raid types to support takeover/reshaping
Add new members to the dm-raid superblock and new raid types to support
takeover/reshape.
Add all necessary members needed to support takeover and reshape in one
go -- aiming to limit the amount of changes to the superblock layout.
This is a larger patch due to the new superblock members, their related
flags, validation of both and involved API additions/changes:
- add additional members to keep track of:
- state about forward/backward reshaping
- reshape position
- new level, layout, stripe size and delta disks
- data offset to current and new data for out-of-place reshapes
- failed devices bitfield extensions to keep track of max raid devices
- adjust super_validate() to cope with new superblock members
- adjust super_init_validation() to cope with new superblock members
- add definitions for ctr flags supporting delta disks etc.
- add new raid types (raid6_n_6 etc.)
- add new raid10 supporting function API (_is_raid10_*())
- adjust to changed raid10 supporting function API
