Fix name clash in do_mknod_internal() due to local variables named
"major" and "minor" shadowing identical macro names.
Also, no need to set the major and minor device for a FIFO inode.

When calling populate_fs, the map for hardlink detection is not
cleaned up between populate_fs invocations, which could lead to
unexpected results if anyone calls populate_fs twice in the same
client program). This doesn't happen right now, but we might as well
clean it up.
The detctor fails if the external directory crosses mountpoints,
so fix that too.

do_write_internal returns errno when ext2 library calls fail; since
errno only reflects the outcome of the last C library call, this will
result in confused callers. Eliminate the naked return since
this results in an undefined return value.

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 this from the genext2fs.

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.

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 ?
