Get rid of the explicit distinction between brick and block numbers.
The format is now defined it terms of fixed 4k blocks. Logs become a
logical structure that's made up of a fixed number of blocks. The
allocator still manages large log sized regions.
Now that we have a working userspace mkfs we can read the supers on
mount instead of always initializing a new file system. We still don't
know how to read items from blocks so mount fails when it can't find the
root dir inode.

The format was updated while implementing mkfs and print in
scoutfs-utils. Bring the kernel code up to speed.
For some reason I changed the name of the item length in the item header
struct. Who knows.

Add a message printing function whose output includes the device and
major:minor and which handles the kernel level string prefix.

This is the initial commit of the repo that will track development
against distro kernels.
This is an import of a prototype branch in the upstream kernel that only
had a few initial commits. It needed to move to the old readdir
interface and use find_or_create_page() instead of pagecache_get_page()
to build in older distro kernels.
