After cleaning up ext2fs_bg_flag_set() and ext2fs_bg_flag_clear(),
we're left with ext2fs_bg_flag_test(). Convert it to
ext2fs_bg_flags_test().

The ext2fs_bg_flag* functions were confusing.
Currently we have this:
void ext2fs_bg_flags_set(ext2_filsys fs, dgrp_t group, __u16 bg_flags);
void ext2fs_bg_flags_clear(ext2_filsys fs, dgrp_t group,__u16 bg_flags);
(_set (unused) sets exactly bg_flags; _clear clears all and ignores bg_flags)
and these, which can twiddle individual bits in bg_flags:
void ext2fs_bg_flag_set(ext2_filsys fs, dgrp_t group, __u16 bg_flag);
void ext2fs_bg_flag_clear(ext2_filsys fs, dgrp_t group, __u16 bg_flag);
A better interface, after the patch below, is just:
ext2fs_bg_flags_zap(fs, group) /* zeros bg_flags */
ext2fs_bg_flags_set(fs, group, flags) /* adds flags to bg_flags */
ext2fs_bg_flags_clear(fs, group, flags) /* clears flags in bg_flags */
and remove the original ext2fs_bg_flags_set / ext2fs_bg_flags_clear.

If the RO compat HUGE_FILE feature flag is set, but the inode's
HUGE_FILE_FL flag is not set, we should still pay attention to the
high 32 bits of the i_blocks filed.

Unfortunately, due to Windows' unfortunate design decision to
configure the hardware clock to tick localtime, instead of the more
proper and less error-prone UTC time, many users end up in the
situation where the system clock is incorrectly set at the time when
e2fsck is run.
Historically this was usually due to some distributions having buggy
init scripts and/or installers that didn't correctly detect this case
and take appropriate countermeasures. However, it's still possible,
despite the best efforts of init script and installer authors to not
be able to detect this misconfiguration, usually due to a buggy or
misconfigured virtualization manager or the installer not having
access to a network time server during the installation process. So
by default, we allow the superblock times to be fudged by up to 24
hours. This can be disabled by setting options.accept_time_fudge to
the boolean value of false in e2fsck.conf. The old
options.buggy_init_scripts is left for backwards compatibility.
Since we are now accepting the 24 hour time fudge by default, there is
no longer a need to install an Ubuntu-specific e2fsck.conf file, so we
can remove it.

E2fsck was not properly printing the i_blocks field in filesystem
corruption messages, and it was not properly checking i_blocks_hi and
i_blocks_lo, either. This commit fixes this.

Non-expert users get confused when they see messages like this:
Illegal block #-1 (2291965952) in inode 176. CLEARED.
So change it to be something a little bit more understandable:
Illegal indirect block (2291965952) in inode 176. CLEARED.

Commit 1d9b818: dumpe2fs: Print more information about the inline journal
caused dumpe2fs to use ext2fs_file_open2(). Previously the file_io
functions were only used by debugfs, so if debugfs was disabled,
file_io was not built. Now that dumpe2fs is also using file_io, we
need to build it unconditionally.

Block size=4096 (log=2)
Fragment size=4096 (log=2)

And warn on block device misalignment:
mke2fs 1.41.9 (22-Aug-2009)
/dev/sdc1 alignment is offset by 32256 bytes.
This may result in very poor performance, (re)-partitioning suggested.

The x86 BT assembly instructure can overshoot the end of a bit array
when testing a bit at the end of the bit array, even if it never needs
to look at those memory locations. This can cause a spurious
segmentation fault. If we allocate a little extra memory, it avoids
this problem. See:
http://faydoc.tripod.com/cpu/bt.htm
This doesn't happen on Linux, probably because of the glibc's malloc()
function works, but apparently it's a major problem on the *BSD
operating systems.

and --with-ld (which never worked), since the first three can be
replaced with CC=, CCFLAGS=, and LDFLAGS= on the configure

parser in libblid has to support .ko.gz extension too.
(Note, I've talked about this problem with Jon Masters and his

modules.dep. BTW, the modules.dep file is deprecated.)

For filesystms that have the extent feature enabled, we need to grab
the use EXT2_IOC_GETFLAGS so that we don't accidentally end up trying
to request clearing the EXT2_EXTENT_FL, which is not supported and
causes the tune2fs -j error out.
Also fix the error returning in ext2fs_add_journal_inode() so it
returns a proper error code if the fstat() or ioctl() calls fail.
