Also added support for "e2fsck -E fragcheck" which issues a
comprehensive report of discontiguous file extents.

This fixes a bug where if there is an entry in the /etc/blkid.tab file
for a particular device (major, minor) number but the filename does
not exist, blkid wouldn't try to find the correct filename.

If the current inode size is less than or equal to the requested inode
size, either explain that shrinking the inode size is not supported,
or that the inode is already the requested size. Also, open the
filesystem provisionally first to do the inode size check and don't
setup up the undo log until we know that we're actually going to
perform the inode resizing operation.

The Makefile should use BUILD_CFLAGS instead of ALL_CFLAGS since it

Disordered inode tables may appear when inode_blocks_per_group is lesser
or equal to the number of groups in a flex group.
This bug can be reproduced with:
mkfs.ext4 -t ext4dev -G512 70G
In that case, you can see with dump2fs that inode tables for groups 510
and 511 are placed just after group 51's inode table instead of being
placed after group 509's inode table.

For people who are compiling mke2fs for their own use outside of a
package manager, we need to make sure the system /etc/mke2fs.conf is
sufficiently up-to-date that it won't cause problems, but at the same
time we don't want to blow away any user-specific customizations.
So if /etc/mk2fs.conf exists, but does not mention ext4dev, we will
move it aside to /etc/mke2fs.conf.e2fsprogs-old and then install the
new mke2fs.conf. If the /etc/mke2fs.conf file exists but does mention
ext4dev, we install the new mke2fs.conf file as
/etc/mke2fs.conf.e2fsprogs-new. In both cases we print a warning
mesage to the user so they can manually update /etc/mke2fs.conf with
any changes if they so desire.

It looks like the right place to check for ino=0 in
ext2fs_read_inode_full() is before creating the inode cache, otherwise
since we set icache[i].ino = 0 in create_icache(), it will match the
loop below and thus we return a wrong value.

It's not needed for e2fsprogs, but one niche distribution likes to use
configure.sh files which can cause GNU make to inappropriately fire an
implicit rule to overwrite the configure file resulting in a fork bomb
leading to the OOM crash.

ext2fs_group_desc_csum_verify() is always checking the bg_checksum (to
make sure it is zero) even when the GDT_CSUM feature is not present.
This is normally OK, but apparently there are filesystems in the wild
where this field has not be initialized to zero.

This is needed so that "make check" works in the e2fsck library even
if the shared libraries are not yet installed, and so that we run
those programs against the version of the libraries built in the build

Solaris's header files are very picky about which C compiler can be
used for SUSv3 conformance. Use of C99 is not compatible with SUSv2
(_XOPEN_SOURCE=500), and C89 is not compatible with SUSv3
(_XOPEN_SOURCE=600). Since we need some SUSv3 functions, consistently
use SUSv3 so that e2fsprogs will build on Solaris using c99.

Gcc only supports __builtin_expect for gcc versions 2.96 and up.
Since it's tricky to check for gcc 2.95 vs 2.96 (and either are only
used on really ancient systems anyway), we only use this optimization
on 3.x and newer versions of gcc.
