btrfs_make_block_groups(), btrfs_alloc_chunk, btrfs_alloc_data_chunk().

Leafsize is deprecated for a long time, and kernel has already updated
ctree.h to rename sb->leafsize to sb->__unused_leafsize.
This patch will remove normal users of leafsize:
1) Remove leafsize member from btrfs_root structure
Now only root->nodesize and root->sectorisze.
No longer root->leafsize.
2) Remove @leafsize parameter from btrfs_setup_root() function
Since no root->leafsize, no need for @leafsize parameter.
The remaining user of leafsize will be:
1) btrfs inspect-internal dump-super
Reformat the "leafsize" output to "leafsize (deprecated)" and
use le32_to_cpu() to do the cast manually.
2) mkfs
We still need to set sb->__unused_leafsize to nodesize.
Do the manual cast too.
3) convert
Same as mkfs, these two superblock setup should be merged later

Build under musl libc fails because of missing PATH_MAX and XATTR_NAME_MAX
macro declarations. Add the required headers.

The caller of make_btrfs does not need to set it, it's for internal use
and can be read after mkfs ends.

The regulare mkfs_btrfs does not anything special about convert and just
passes the arguments. Make that two functions.
