Implement ocfs2_direct_IO_write. Add the inode to orphan dir first, and
then delete it once append O_DIRECT finished.
This is to make sure block allocation and inode size are consistent.

If one node has crashed with orphan entry leftover, another node which do
append O_DIRECT write to the same file will override the
i_dio_orphaned_slot. Then the old entry won't be cleaned forever. If
this case happens, we let it wait for orphan recovery first.

Add functions to add inode to orphan dir and remove inode in orphan dir.
Here we do not call ocfs2_prepare_orphan_dir and ocfs2_orphan_add
directly. Because append O_DIRECT will add inode to orphan two and may
result in more than one orphan entry for the same inode.

Prepare some interfaces which will be used in append O_DIRECT write.

Hi Joseph,
Did this version make any performance improvement with v5? I tested v5,
and it didn't improve performance with original buffer write + sync.
Thanks,
Junxiao.

Intruduce a bit OCFS2_FEATURE_RO_COMPAT_APPEND_DIO and check it in

Currently in case of append O_DIRECT write (block not allocated yet),
ocfs2 will fall back to buffered I/O. This has some disadvantages.
Firstly, it is not the behavior as expected.
Secondly, it will consume huge page cache, e.g. in mass backup scenario.
Thirdly, modern filesystems such as ext4

No performance difference between these two versions.
But we have tested with fio before,
Complte the rest request thourgh buffer io after direct write performed.

Now we can do direct io and do not fallback to buffered IO any more in
case of append O_DIRECT write.

Normal xfs style would be to keep the static void on a separate line,
as well as the arguments, e.g.
OK, will change it to conform to the XFS coding style.
