addition, it adds to check .i_gc_failures and do resetting in fsck.

This patch introduces lost_found feature to fsck. If a file is found
unreachable by fsck. Fsck tries to reconnect the file to lost+found
directory:
1. Scan all unreachable file inodes, ignore non-inodes ones and
directories.
2. Check them and fix incorrupted data to make sure filesystem
metadata (mainly counters and main/nat bitmap) are all consistent.
3. Reconnect these files to lost+found. If lost+found does not exist,
create it first. During reconnecting, expand lost+found's dentry
block automatically. Reconnected files are renamed after its ino
number.
4. If reconnect fails drop the node and restore filesystem metadata.

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_atime_extra | |
| .i_ctime_extra | |
| .i_mtime_extra |<----+
| .i_inode_cs |<----- store blkaddr/inline from here
| .i_xattr_cs |
| ... |
+--------------------+
| |
| block address |
| |
+--------------------+
| .i_nid |
+--------------------+
| node_footer |
| (nid, ino, offset) |
+--------------------+

Use f2fs_dentry_ptr structure to indicate inline dentry structure as
much as possible, so we can wrap inline dentry with size-fixed fields
to the one with size-changeable fields. With this change, we can
handle size-changeable inline dentry more easily.

It is reported that fsck.f2fs behaves abnormally when running on MIPS32
rel 2 big endian cpu, since incorrect endianness. So let's correct all
endianess issues of f2fs-tools.

This patch implements loading files into the existing partition.
For example,
# sload.f2fs -f ./ /dev/sdb1
Then, all the directories and files will be loaded into /dev/sdb1.
By default, newly files should have inline_data and inline_xattr, if possible.
