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.

Since the block group checksums depend on the UUID, we need to update
the block group checksums when setting the UUID. We only do so if all
of the checksums are correct, however.

Pass in -rpath-link option to the linker so that blkid will build
correctly on systems that don't have libcom_err.so.2 installed.
Fix debugfs to only try to link with -ldl when building without shared
libraries; with ELF shared libraries, the library which requires -ldl
(libss.so) can required the library dependency itself.
Fix how we build tune2fs.static so that we use @LDFLAG_STATIC@, via
$(LDFLAGS_STATIC), instead of hard-coding the use of -static.

The rec_len field in the directory entry is 16 bits, so if the

Option specifiers must be escaped so the are printed as minus signs

Many people are forgetting to update their mke2fs.conf file, and this

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.

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.

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.

If creating a an external journal via "mke2fs -O journal_dev",
override the fs_type list (i.e., "ext2", "small"), and replace it with
an fs_type list of "journal". This will prevent external journals
smaller than 512MB from being created with a block size of 1k, which
is not very useful and leads to much confusion.
