Update the format header and add a man page which describes the
corruption messages that the kernel module can spit out.

Make the changes to support the new small key struct. mkfs and print
work with simpler keys, segment items, and manifest entries. The item
cache keys ioctl now just needs to work with arrays of keys.

With the removal of the size index items we no longer have to print them
or be able to walk the index. mkfs only needs to create a meta seq
index item for the root inode.

Update the calculation of the largest number of btree blocks based on
the format.h update that provides the min free space in parent blocks
instead of the free limit for the entire block.

The kernel format.h has built up some changes that the userspace utils
don't use. We're about to start enforcing exact matching of the source
files at run time so let's bring these back in sync.

The kernel key printing code was refactored to more carefully print
keys. Import this updated code by adding supporting functions around it
so that we don't have to make edits to it and can easily update the
import in the future.

format.h and ioctl.h are copied from the kernel module. It had a habit
of accidentally using types that aren't exported to userspace. It's
since added build checks that enforce exported types. This copies the
fixed use of exported types over for hopefully the last time.

Our item cache protocol is tied to holding DLM locks which cover a
region of the item namespace. We want locks to cover all the data
associated with an inode and other locks to cover the indexes. So we
resort the items first by major (index, fs) then by inode type (inode,
dirent, etc).

Manifest entries and segment allocation bitmap regions are now stored in
btree items instead of the ring log. This lets us work with them
incrementally and share them between nodes.

Add support for the inode index items which are replacing the seq walks
from the old btree structures. We create the index items for the root
inode, can print out the items, and add a commmand to walk the indices.

Add mkfs and print support for the simpler rings that the segment bitmap
allocator and manifest are now using. Some other recent format header
updates come along for the ride.

The segment item struct used to have fiddly packed offsets and lengths.
Now it's just normal fields so we can work with them directly and get
rid of the native item indirection.

Make sure that the manifest entries for a given level fully
cover the possible key space. This helps item reading describe
cached key ranges that extend around items.

Update mkfs and print to describe the ring blocks with a starting index
and number of blocks instead of a head and tail index.

Make a new file system by writing a root inode in a segment and storing
a manifest entry in the ring that references the segment.
