When increasing inode size if we find that the new block
that we needed to increase the inode table size is a bad
block we fail. This make sure we don't end up with a corrupt
file system when doing inode resize on a file system having
bad blocks.

With file system formated for RAID arrays we can have inode bitmap
and block bitmap after inode table. Make sure we move them around
properly when doing inode resize.

This removes the metadata block bitmap and makes the error handling
simpler. It also check for the enospc with the correct number needed
blocks. Also added specific error messages. We need to run e2undo
only if we start modiyfing inode, group desc and inode table.

Add an option to switch between the private (in-tree) libblkid and
public (in-system installed) library. The private version is still
enabled by default.
If --disable-libblkid is specified the findfs(8) program, which is a
variant of tune2fs, is also not built or installed.

If a filesystem is built with the stride extended-option (which is
often used in RAID filesystems to make sure the block and inode
allocation bitmaps don't end up hitting one disk platter harder than
the rest), this can cause tune2fs -I to corrupt the filesystem because
it fails to handle the case where the allocation bitmaps are located
after the inode table, where the inode table needs to grow. Handle
this case correctly.

With flex_bg usually the inode table for most block groups are packed
right against each other, so expanding the inode table size needs
special handling that's not currently in tune2fs.

When running "tune2fs -I 256" on moderate to large filesystems, the
time required to run tune2fs can take many hours (20+ before some
users gave up in disgust). This was due to some O(n**2) and O(n*m)
algorithms in move_block() and inode_scan_and_fix(), respectively.

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.

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.

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.

Add new option -I <inode_size> to tune2fs. This is used to change the
inode size. The size need to be multiple of 2 and we don't allow to
decrease the inode size.
As a part of increasing the inode size we increase the inode table
size. We also move the used data blocks around and update the
respective inodes to point to the new block
tune2fs uses the undo I/O manager when migrating to large inode. This
helps in reverting the changes if end results are not correct. The
environment variable TUNE2FS_UNDO_DIR is used to indicate the
directory within which the tdb file need to be created. The file will
be named tune2fs-<device-name> If TUNE2FS_UNDO_DIR is not set
/var/lib/e2fsprogs is used

We need to set tm_isdst to -1 so that mktime will automatically
determine whether or not daylight savings time (DST) is in effect.
Previously tm_isdst was set to 0, which caused mktime to interpret the

Clearing SPARSE_SUPER is dangerous; it can result in a filesystem
which e2fsck can't fix easily. Since there is very few good reasons
for wanting to turn this feature off, disable tune2fs's abiity to do
this. Users who really want this can use debugfs.
Also, deprecate the tune2fs -s option. Remove it from the man page
and usage message.
