The fuzzers from oss-fuzz in projects/e2fsprogs/fuzz (as of commit
78ecd3f07fca with some slight modifications for better error
reporting) have been placed in the tests/fuzz directory and the
configure script now supports a new option --enable-fuzzing which will
build these fuzzers using clang's -fsanitize=fuzzer command line
option.
In general, some sanitizer such as --enable-addrsan or --enable-ubsan
(to enable ASAN or UBSAN, respectively) should be enabled alongside
--enable-fuzzing.
A typical configure command to build the fuzzers might be:
configure CC=clang CXX=clang++ CFLAGS=-g --enable-fuzzing --enable-addrsan

This also removes the built-in "intl" directory as this is now
considered deprecated by the gettext package. This means that we
won't try to use an internal version of gettext if it's not installed
on the build system. We will simply disable NLS support in that case.

In the case where mkdir -p is not thread-safe (for example, if the
build environment is using busybox's mkdir) the configure script will
fall back to the slow (but safe) install-sh script. In that case
MKDIR_P will be using a relative pathname; so we can't use speed
optimization of defining configure substitutions in MCONFIG.in, since
the substitution will be different depending on depth of the
subdirectory in the Makefile.in file.

The e2fsprogs-libs-1.44.x.tar.gz subset distribution had a hack so
that "make install" would install the libraries via an implied "make
install-libs" --- since after all the tarball had was just the
libraries.
This commit makes "make install" behave the same was as the
e2fsprogs-libs distribution in the case of "configure --enable-subset"

There's no point creating two separate tarfiles. It's not clear
anyone was actually using the subset tarball --- and if they are, they
can replace it by the full source distribution and using the
--enable-subset option.

It adds extra complexity for not much gain, and stands in the way of

Implement online fsck for ext* filesystems which live on LVM-managed
logical volumes. The basic strategy mirrors that of e2croncheck --
create a snapshot, fsck the snapshot, report whatever errors appear,
remove snapshot. Unlike e2croncheck, this utility accepts any LVM
device path, knows about snapshots running out of space, and can call
fstrim having validated that the fs metadata is ok.

This fixes a number of incompatibilities which caused maint branch to
fail to build on on FreeBSD. Also fix the Makefile in the tests
directory so that "make -jN check" works correctly on FreeBSD.
Previously the Makefile in the tests directory used a construct which
was specific to GNU Make, which which silently expanded to an empty
list, which caused "make check" to be a no-op when running using BSD's
pmake. This Makefile has been changed to use the != macro assignment
syntax which is common to GNU make and BSD pmake. It's technically
not completely portable (it will not be recognized by Solaris's ccs
make, for example), but most other operating systems ship GNU make
(Solaris, AIX), or BSD pmake (*BSD, Mac OS) as either the primary or
alternative make utility that this should an acceptable compromise,
since it makes running all of tests using something like "make -j8
check" or "make -j16 check" run *much* faster.
There are still some caveats if using BSD pmake; in particular, if the
configure script is run on a system which has GNU make (installed as
gmake on FreeBSD for example), the configure script will find it, and
enable some GNU make features in the Makefile, and the generated
makefiles *must* be built using gmake. However, if isolated build
jail / chroot is used which only has pmake, the Makefiles should now
work with pmake.

Commit 832cb612: "e2fsprogs: add (optional) sparse checking to the
build" breaks systems that are not using GNU make. In addition, it
breaks if the developer tries to build in a subdirectory (i.e., if he
or she tries running "make" in the misc or e2fsck or lib/ext2fs
directory), since CHECK_CMD is not set.
Fix this by moving the sparse setup to MCONFIG.

Run sparse against source files when building e2fsprogs with 'make C=1'. If
instead C=2, it configures basic ext2 types for bitwise checking with sparse,
which can help find the (many many) spots where conversion errors are
(possibly) happening.

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 the quota library (ported form Jan Kara's quota-tools) in
e2fsprogs in order to make quotas as a first class supported feature in Ext4.
This patch also provides interface in lib/quota/mkquota.h that will be used by
mke2fs, tune2fs, e2fsck, etc. to initialize and update quota files.
This first version of the quota library does not support reading existing quota
files. This support will be added in the near future.
Thanks to Jan Kara for his work on quota-tools. Most of the files in this patch
are taken as-is from quota tools and were simply modified to work with
libext2fs in e2fsprogs.
