Change all of the e2fsprogs programs to use the newer add_error_table()
and remove_error_table() interfaces instead of the much older
initialize_*_error_table() function.

Badblocks now interprets last_block argument as the last block to check,
instead of the number of blocks to check, to be consistent with the
badblocks man page.

Fix revision 0 error checking so that it doesn't give spurious error
when the user gives a command-line option of "-O none".Add error
checking so that "-r 0 -j", "-r 0 -s 1", and "-r 0 -E resize=XXX" will
print an explanatory error message and abort.

There were still some %d's lurking when we print blocks & inodes; also
many of the counters in the e2fsck_struct were signed, and probably
need to be unsigned to avoid overflows.

Add a new functiom, e2p_percent(), which correct calculates the percentage
of a number based on a given percentage, without worrying about overflow
issues. This is used where we calculate the number of reserved blocks using
a percentage of the total number of blocks in a filesystem.
Based on patches from Eric Sandeen, but generalized to use this new function.

Add a new function, ext2fs_div_ceil(), which correctly calculates a division
of two unsigned integer where the result is always rounded up the next
largest integer. This is used everywhere where we might have
previously caused an overflow when the number of blocks
or inodes is too close to 2**32-1.

Disambiguate the use of "-F" (force) flag for mke2fs to avoid dangerous
situations. The use of -F is needed for regular backing files and
for filesystems on whole block devices. It should NOT be confused
with mke2fs on an apparently-mounted or in-use filesystem.

This patch allows "inode_size" to be specified in the mke2fs.conf file,
and always compiles in the "-I" option. In addition, it disallows
specifying the inode size on rev 0 filesystems, though I don't think
this was much of a danger anyways.

The exlcusive device safety check that was added inadvertently broke
e2fsck -cc and mke2fs -cc since e2fsck and mke2fs hold the device
in exclusive access when badblocks is run. So we add a private option
to badblocks, -X, which is passed by e2fsck and mke2fs to badblocks
to indicate that it is OK to skip the EXT2_MF_BUSY checks.

This feature is initially intended for testing purposes; it allows an
ext2/ext3 developer to create very large filesystems using sparse files
where most of the block groups are not initialized and so do not require
much disk space. Eventually it could be used as a way of speeding up
mke2fs and e2fsck for large filesystem, but that would be best done by
adding an RO_COMPAT extension to the filesystem to allow the inode table
to be lazily initialized on a per-block basis, instead of being entirely initialized
or entirely unused on a per-blockgroup basis.

and changes "bad" to "invalid" in some messages to avoid confusion with

we changed ext2fs_create_resize_inode to always create the resize inode,
even when s_reserved_gdt_blocks is zero. Mke2fs and e2fsck was calling
ext2fs_create_resize_inode() unconditionally, and depending on
s_reserved_gdt_blocks to be zero, instead of explicitly checking the
resize_inode feature.

(The patch from Fedora e2fsprogs-1.35-11.2 claimed it
worked, but it was a placebo, despite the claim that it
worked in the usage message.)
Mke2fs has been modified to honor the MKE2FS_SKIP_PROGRESS,
MKE2FS_DEVICE_SECTSIZE, and MKE2FS_SKIP_CHECK_MSG in order

removed. E2fsck will now fix HTREE corruptions in preen mode, and
mke2fs will not create filesystems with the dir_index flag set

tune2fs.c (update_feature_set): Allow directory indexing flag to
be set. If so, set the default hash to be TEA, and
initialize the hash seed to a random value.
