This patch adds an option 'extra_attr' in mkfs for enabling v2 f2fs
inode format in kernel codes.

Also this patch makes fsck to support recognize v2 inode format,
below is v2 format description:

Original one:

struct f2fs_inode {
...
struct f2fs_extent i_ext;
__le32 i_addr[DEF_ADDRS_PER_INODE];
__le32 i_nid[DEF_NIDS_PER_INODE];
}

Extended one:

struct f2fs_inode {
        ...
        struct f2fs_extent i_ext;
union {
struct {
__le16 i_extra_isize;
__le16 i_padding;

};
__le32 i_addr[DEF_ADDRS_PER_INODE];
};
        __le32 i_nid[DEF_NIDS_PER_INODE];
}

Once F2FS_EXTRA_ATTR is set, we will steal four bytes in the head of
i_addr field for storing i_extra_isize and i_padding. with i_extra_isize,
we can calculate actual size of reserved space in i_addr, available
attribute fields included in total extra attribute fields for current
inode can be described as below:
