This code is partially derived from patches from David Turner to allow
debugfs to properly support extended timestamps.

After checking inline data in ext2fs_inode_have_valid_blocks2() we won't
traverse the block in do_lsdel() function. But if an inode has inline
data we also need to report it.

After applied this commit (a7f4c635), we have banned to traverse blocks
for an inode which has inline data because no block belongs to it. But
before calling this function, we need to check inline data flag. This
commit add a sanity check ext2fs_inode_has_valid_blocks2() to fix them
except that ext2fs_expand_dir because it will be fixed by another patch.
Meanwhile in this commit it fixes a bug that when we kill a file we
could leak an inode.

Clean up the formatting of the debugfs(8) man page:
- add command aliases to the main descriptions
- use bold for sub-commands and italics for their arguments
- remove trailing spaces
- add "dirty" sub-command
- clarify "block_dump" and "zap_block" sub-commands

The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and
this was starting to cause some tools heartburn. It also made "make
V=1" almost useless, since trying to following the individual commands
run by make was lost in the noise of all of the defines.
So fix this by putting the configure-generated defines in lib/config.h
and the directory pathnames to lib/dirpaths.h.
In addition, clean up some vestigal defines in configure.in and in the
Makefiles to further shorten the cc command lines.

Use the EXT2_I_SIZE() macro consistently to access the inode size.
The i_size/i_size_high combination is open coded in several places.

Pass BLOCK_FLAG_READ_ONLY to ext2fs_block_iterate2() so that debugfs,
e2image, and tune2fs will work well with filesystems containing
extents.

Mke2fs is supposed to set the uid/gid ownership of the root directory when
a non-rooot user creates the filesystem. This wasn't working correctly
if the uid/gid was > 16 bits. In additional, debugfs wasn't displaying
large uid/gid's correctly. This patch fixes these two programs.

Generalize the time parsing code and move it to
util.c:string_to_time(). Add new command, set_current_time, which
sets the time used to set the filesystems's time fields.

1) The modify_inode command was core dumping if no filesystem was open.
2) The lsdel command command now uses the pager.
Also updated the Makefile.in file with "make depend".
recover deleted files. The lsdel command now takes an optional
argument which allows the user to only see the most recently
deleted files. Also added a new command, undel, which automates
undeleting a deleted inode and linking it back to a directory.
Also added an optional count argument to the testb, freeb, setb,
and find_free_block commands. The ls command now takes a new
option, -d, which lists deleted directory entries.
Factored out out commonly used code into utility subroutines
for ease of maintenance and to make the executable size smaller.
If a file is created with "dd if=/dev/zero of=<file> bs=1k skip=2047M"
it is created properly by the kernel, but fails to be seen properly
by debugfs - the blocks are not shown by stat <inum>, nor can they
be found by icheck. This change fixes that.
debugfs.c, debugfs.h, dump.c, icheck.c, ls.c, lsdel.c, ncheck.c,
setsuper.c, util.c: Change ino_t to ext2_ino_t. Fix a few minor
gcc-wall complaints while we're at it.
block.c (ext2fs_block_iterate3): Make the ref_offset field contain the
offset into the inode.i_blocks array when ref_block is zero. Since we
haven't done a formal release of e2fsprogs since block_iterate2 was
first introduced, I removed block_iterate2, and renamed block_iterate3
to be block_iterate2.
bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c, expanddir.c,
ext2fs.h, ext2fsP.h, read_bb.c: Change use of block_iterate and
block_iterate2 to block_iterate2 with the new prototype for the
interator function. (using blkcnt_t forr blockcount)
ChangeLog, debugfs.c, ls.c, lsdel.c:
debugfs.c, ls.c, lsdel.c: Add support for large files. (The high 32
bits share space with the i_dir_acl field.)
