This patch adds support for setting the quota feature in superblock
and allows selectively creating quota inodes (user or group or both)
in the superblock. Currently, modifying the quota feature is only
supported when the filesystem is unmounted.
Also, when setting the quota feature, tune2fs will use aquota.user or
aquota.group file inode number in superblock if these files exist.
Otherwise it will initialize empty quota inodes #3 and #4 and use them.
Here is how it works:
# Set quota feature and initialize both (user and group) quota inodes
$ tune2fs -O quota /dev/ram1
# Enable only one type of quota
$ tune2fs -Q usrquota /dev/ram1
# Enable grpquota, disable usrquota
$ tune2fs -Q ^usrquota,grpquota /dev/ram1
# Clear quota feature and remove quota inodes
$ tune2fs -O ^quota /dev/ram1

mke2fs also creates quota inodes (userquota: inode# 3 and
groupquota: inode #4) inodes while creating a filesystem when 'quota'
feature is set.
# To set quota feature and initialize quota inodes during mke2fs:
$mke2fs -t ext4 -O quota /dev/ram1

lib/ext2fs/Makefile.in had a buggy entry for blkmap64_ba.c in $(SRCS),
which caused this source file to not have a valid Makefile dependency
entry, so blkmap64_ba.o would not get rebuilt when it needed to be.
Also updated the Makefile dependency for the misc directory while
we're at it.

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.

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.

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.

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.

Adapted from the SuSE patch, but fixes a number of very serious
problems with the patch in SLES:
1) This changeset uses -M instead of -m; most lowercase options are
reserved for use by the filesystem-specific fsck programs. All new
fsck options must be upper case.
2) This changeset will skip the root filesystem in "fsck -AM", which
the SLES patch will not do.
3) Loading /proc/mounts into the fs_info can cause -t opts matching to
malfuction. So this changeset uses a simplified version of the
ismounted.c function from the ext2fs library.

People are getting surprised by mke2fs creating filesystems with
different defaults than earlier versions of mke2fs if mke2fs.conf is
not present. Having gotten two complaints about ramdisks getting
created by with 4k blocksizes which then blow up when the ramdisk is
mounted with a "Magic mismatch, very weird" error message from the
kernel, let's fix this by making sure mke2fs has a built-in version of
mke2fs.conf file. People can still override the built-in version of
mke2fs.conf by editing /etc/mke2fs.conf, but this maintains the
previous behavior.
