We will add a -d option which will be used for adding the files from a
given directory to the filesystem, it is similiar to genext2fs, but
genext2fs doesn't fully support ext4.
* We already have the basic operations in debugfs:
- Copy regular file
- Create directory
- Create symlink
- Create special file
We will move these operations into create_inode.h and create_inode.c,
then let both mke2fs and debugfs use them.
* What we need to do are:
- Copy the given directory recursively, this will be done by the
populate_fs()
- Set the owner, mode and other informations
- Handle the hard links
TODO:
- The libext2fs can't create the socket file (S_IFSOCK), do we have a
plan to support it ?

Use opendir() and readdir() to read the native directory, then use
lstat() to identify the file type and call the corresponding function to
add the file to the filesystem, call the populate_fs() recursively if it
is a directory.
NOTE: the libext2fs can't create the socket file.

Create the inode and save the native inode number when we meet the hard
link (st_nlink > 1) at the first time, use ext2fs_link() to link the
name to the target inode number when we meet the same native inode
number again.
This algorithm is referred from the genext2fs.

* Use the functions in misc/create_inode.c, and remove the duplicated
code.
* The CREATE_INODE_DEPS in the debugfs/Makefile.in is used for recording
create_inode.o's depends which is from misc/Makefile.in, we have to
recompile create_inode.o because we need it to print more messages when
it is used by debugfs, just like we recompile e2freefrag.o, but it seems
that the e2freefrag.o's depends in debugfs/Makefile.in is incorrect, it
would not rebuild when its depends (e.g.: lib/config.h) is changed,
which would cause unexpected errors. Make duplicated code in
debugfs/Makefile.in and misc/Makefile.in is not a good idea, maybe we'd
better define CREATE_INODE_DEPS in the top Makefile, I'd like to send
another patch and fix the e2freefrag if you are fine with it.

These patches should be enabled at the same time, so enable them in a
single commit, and thus we can disable it easily.

We used populate-extfs.sh which invoked the debugfs to create the image,
now the mke2fs' option "-d root-directory" can do the same thing, and
which is more faster, for example, the core-imag-sato:
* In the past:
$ time mke2fs -t ext4 rootfs.ext4
real 0m0.249s
user 0m0.036s
sys 0m0.132s
$ time populate-extfs.sh /path/to/rootfs/ rootfs.ext4
real 0m29.355s
user 0m10.637s
sys 0m5.544s
* Now:
$ time mkfs.ext4 -F -d /path/to/rootfs/ rootfs.ext4
real 0m6.338s
user 0m3.824s
sys 0m1.356s
More than 25 seconds are saved.
