fibmap: include f2fs_fs.h before other header files
GCC 7.2.0 is unhappy with the usage of major/minor:
fibmap.c: In function ‘print_stat’:
fibmap.c:70:13: warning: In the GNU C Library, "major" is defined
by <sys/sysmacros.h>. For historical compatibility, it is
currently defined by <sys/types.h> as well, but we plan to
remove this soon. To use "major", include <sys/sysmacros.h>
directly. If you did not intend to use a system-defined macro
"major", you should undefine it after including <sys/types.h>.
printf("dev [%d:%d]\n", major(st->st_dev), minor(st->st_dev));

f2fs-tools: enhance on-disk inode structure scalability
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_extra_end[0];
};
__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:
+--------------------+
| .i_mode |
| ... |
| .i_ext |
+--------------------+
| .i_extra_isize |-----+
| .i_padding | |
| .i_prjid | |

| .i_inode_cs |<----- store blkaddr/inline from here
| .i_xattr_cs |

f2fs-tools: fix the wrong message when errno is EBUSY
If f2fs is unmounted with the -l option, the process can still use the
file system. In this case, the command mkfs.f2fs, fsck.f2fs, dump.f2fs,
defrag.f2fs, resize.f2fs and sload.f2fs failed due to the device is in
use by the system. At the moment f2fs is already not mounted, so it is
wrong to print error message "Error: Not available on mounted device!",
this patch fixes it.

f2fs-tools: support to set and recognize CP_TRIMMED_FLAG
During mkfs, once we have issued discard for all device, we can set
CP_TRIMMED_FLAG in cp pack, this can make kernel module to record
undiscard blocks correctly, it will help to avoid unneeded discard.
Also this patch makes f2fs-tools be with the ability of recognizing
that new flag.

fsck.f2fs: sanity check segno and blk_off when building curseg array
segno and blk_off were read from input image without sanity check. This
could lead to buffer overflow when accessing internal arrays like SIT
sentries and seg_entry cur_valid_map.
