    Add non-GPL ext2 filesystem (port from FreeBSD)
    
    The new ext2 will replace the existing sys/gnu/vfs/ext2fs in future,
    which is known to have lots of issues. This is already better than
    sys/gnu/vfs/ext2fs in many ways, but will keep it as an option for now
    as there seems to be htree dirents and/or vop_readdir related bugs.
    
    The new implementation supports ext3 htree dirents. Read support for
    ext4 extents which exists in FreeBSD ext2 isn't implemented yet (TODO).
    ACL/xattr are unsupported, and likely never will be.
    
    With exception of DragonFly VFS specific part that can't reuse FreeBSD
    code (vfsops, many vnops, bread/getblk/bio i/f difference, etc),
    the new ext2 is designed to be close to upstream as much as possible.
    The code is there for a reason to make clear the *real* diff without
    introducing nonfunctional diff noises.
