If the file system has a blocksize less than 64k, then don't use the
extended rec_len encoding, to be consistent with what the kernel will
do.

The getopt() function returns an int, not a char. On systems where the
default char is unsigned (like ppc), we get weird behavior where -1 is
truncated to 0xff but compared to (int)-1.
Also fix this same bug for two test programs, test_rel and iscan,
which aren't currently used at the moment.

Use a standard, fixed mke2fs.conf file so that if downstream
distributions want to change the mke2fs.conf which is distributed in
the RPM or dpkg file, it won't screw up the regression tests.

Add test to make sure e2fsck doesn't end up detaching and sending to
lost+found inodes which are in an bg_itable_unused_region (e.g. if
there was a power failure and bg_itable_unused wasn't updated because
journaling wasn't enabled).

Some kernels will crash if EOFBLOCKS_FL is set when it is it not
needed, and this if it is left set when it isn't needed, it is a sign
of a kernel bug.

Duplicate directory entries were not necessarily getting found and
fixed for non-indexed directories, since we were sorting these
directories by inode number, and the duplicate entry code assumed the
entries were getting sorted by name or directory name hash.

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.

Some people don't want to see the concise "kernel-style" make output.
This configure option allows build engines that want to see the full
set of commands executed by the makefile to get what they want. Most
people will find this more distracting than useful, unless they need
to debug the Makefiles.
(It is not necessary to rerun configure to enable this verbose make
output temprarily; if a developer wants to do a quick debug of a
directory's makefile, he or she can simply edit the definition of the
$(E) and $(Q) variables in the Makefile; instructions can be found in
the MCONFIG file which is included in at the beginning of every
Makefile.)

The e2fsprogs makefiles were using the same Makefile variable
LIBCOM_ERR for the link-line arguments as well as the dependencies.
Since LIBCOM_ERR can now include non-file arguments such as
"-lpthread", we need to use a separate DEPLIBCOM_ERR variable that
only has build file dependencies.
Do the same thing for STATIC_LIBCOM_ERR and PROFILED_LIBCOM_ERR.

Previously e2fsprogs interpreted 0 for a rec_len of 65536 (which could
occur if the directory block is completely empty in 64k blocksize
filesystems), while the kernel interpreted 65535 to mean 65536. The
kernel will accept both to mean 65536, and encodes 65535 to be 65536.
This commit changes e2fsprogs to match.
We add the encoding agreed upon for 128k and 256k filesystems, but we
don't enable support for these larger block sizes, since they haven't
been fully tested.

Gcc is too stupid to realize that:
const char *usage="String which has no percent signs";
com_err(progname, 0, usage);
is OK. I refuse to bow to stupidity with:
com_err(progname, 0, "%s", usage);
but I will use the string directly for the sake of people who like to
build with -Werror=format-security.

E2fsck could to do more damage to a filesystem by trying to relocate
inode tables due to corrupted block group descriptors, and the
relocation could seriously damage the filesystem.
This patch enhances ext2fs_check_desk() so it detects more
self-inconsistent block group descriptors, including the cases where
e2sck might be tempted to relocate the inode table, and reports the
block group descriptors as invalid; this will cause e2fsck to attempt
to use the backup superblocks, which hopefully have not been trashed.

When calculating the number reserved blocks, use floating point for
better accuracy, since for big filesystems it really makes a
difference. In addition, mke2fs and tune2fs accepts a floating point
number from the user, so they should provide that level of accuracy.

Provide mke2fs with a much more sophisticated system for controlling
configuration parameters of a newly created filesystem based on a
split filesystem and usage type system. The -t option to mke2fs was a
deprecated alias to -c; it now specifies a filesystem type (ext2,
ext3, ext4, etc.), while the -T option can now be a comma separated
usage list.
