We return __u16 in the kernel, as this is actually the size of
btrfs_qgroup_level. Adjust the existing helpers and update all the
callers to deal with the new size appropriately. This will make syncing
the kernel code cleaner.

Add the on disk definitions for the block group tree. This will be part
of the super block so we need to add the appropriate helpers to the
super block, as well as adding it to the backup roots.

There are missing incompat bits in the util headers:
- metadata_uuid
- raid1c34
- zoned
This does not change library ABI, no version change needed.

The BTRFS_DEV_REPLACE_ITEM_STATE_x series defines as shown in [1] are
unused in both kernel and btrfs-progs.
[1]
btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_FINISHED 2
btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_CANCELED 3
btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_SUSPENDED 4
Further the BTRFS_DEV_REPLACE_ITEM_STATE_x values are different form its
counterpart BTRFS_IOCTL_DEV_REPLACE_STATE_x series as shown in [2].
[2]
btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_SUSPENDED 2
btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_FINISHED 3
btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_CANCELED 4
So this patch deletes the BTRFS_DEV_REPLACE_ITEM_STATE_x altogether,
they're not used by anything.

Systems with older kernels won't have these available, and the copies in
btrfs-progs aren't quite compatible, so for now, let's just copy these
in. We can potentially deduplicate some of this in the future.
