The quota code required that we included dict.o in libsupport.a, so we
might as well just move dict.c and dict.h to lib/support, and then
have e2fsck use the version of dict.c in libsupport.a. This
simplifies the build system and eliminates having two identical copies
of dict.o floating around in the build tree.

This is the initial implementation of a FUSE server based on

OS that FUSE supports (and doesn't already have a native driver), such
as MacOS X, BSDs, and Windows. The code requires FUSE API v28, which
is available in Linux fuse and osxfuse releases that are available as

There are interfaces that are used by mke2fs.c and tune2fs.c which are
in quotaio.h, and some future changes will be much simpler if we can
combine the two header files together. Also the guard #ifdef for
mkquota.h was incorrect, which caused problems when both header files
needed to be included.
Also remove quota.pc and installation rules for libquota, since this
library is never going to be something that we can export externally
anyway. Eventually we'll want to clean up the interfaces and move the
external publishable interfaces to the libext2fs library, and then
rename what's left from libquota.a to libsupport.a for internal use
only.

Newer versions of autoconf pull in AC_PROG_GCC as part of
AC_CANONICAL_HOST. So we need check for WITH_DIET_LIBC earlier in
configure.in.
Also, e2fsprogs now needs functions which are found in diet libc's
compat library. So add support for autoconf's LIBS function, and
automatically set libs to include -lcompat.
Finally, disable compiling e4defrag by deault if --with-diet-libc is
specified because the program has too many glibc dependencies.

The Build Log Hardening Check is a debian tool which scans the output
of a package build making sure that the security hardening flags are
used when compiling and linking all of binaries in a package.
For the most part we were passing CFLAGS, CPPFLAGS, and LDFLAGS down
to the compiler and link commands, but there there were one or two
exceptions. In addition, there where a few places in "make install"
where the V=1 option was not being honored, which triggered blhc
warnings since it couldn't analyze those commands.
The e2fsck.static was the only binary that was not getting built and
packaged with the hardening flags, but I've fixed all of the blhc
warnings so in the future it will be obvious if we regress.

to use either mke2fs.conf.in or mke2fs.conf.custom.in (if it is
present). If there is custom configuration file, it's likely that it
is very different from the upstream mke2fs.conf.in, so by having the
separate mke2fs.conf.custom.in file, it minimizes merge conflicts if
the upstream mke2fs.conf file changes.

The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and
this was starting to cause some tools heartburn. It also made "make
V=1" almost useless, since trying to following the individual commands
run by make was lost in the noise of all of the defines.
So fix this by putting the configure-generated defines in lib/config.h
and the directory pathnames to lib/dirpaths.h.
In addition, clean up some vestigal defines in configure.in and in the
Makefiles to further shorten the cc command lines.

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
