This commit removes the C header files from the EXTRA_DIST variables
and instead assigns them to the SOURCE variable of the respective
components they belong to.
This takes care of having them distributed in the release tar ball and
helps with dependency tracking a little.

The ubihealthd depends on sys/random.h , which is not present on some
older systems. Build ubihealthd only if sys/random.h is present.

I added ZSTD support to mkfs.ubifs and compared the ZSTD results with
zlib/lzo and the available ZSTD compression levels. The results are in

The UBIFS image was created via
mkfs.ubifs -x $Comp -m 512 -e 128KiB -c 2200 -r $image $out
I used "debootstrap sid" to create a basic RFS and the results are in
the `image' column. The image2 column denotes the results for the same
image but with .deb files removed.
The time column contains the output of the run time of the command.
ZSTD's compression level three is currently default. Based on the
compression results (for the default level) it outperforms LZO in
run time and compression and is almost as good as ZLIB in terms of
compression but quicker.
The higher compression levels make almost no difference in compression
but take a lot of time.
The compression level used is the default offered by ZSTD. It does not
make sense the higher levels.

This implements/adds selinux labelling support to mkfs.ubifs
utility. It adds an extra option in configure to enable
selinux labelling support and then finally in mkfs.ubifs adds
an extra option to pass the file_contexts which is looked up
for filesystem file labels.
- Default behavior is kept without selinux so as to not break existing
support where selinux library/headers may not be present.
- If this is configured with --with-selinux then XATTR from the
file_contexts(passed with --selinux option while mkfs.ubifs)
will be taken and not from the host file's xattr.
This is done to avoid the problem where the host OS may have
selinux enabled and hence same xattr names will be present in both
host filesystem files and from the --selinux=file passed.
So the existing behavior is kept mutually exclusive and preference
is given to selinux xattrs (if configured with --with-selinux).

This patch borrows the compiler.m4 script from util-linux to check
for compiler support of a number of warning flags and sets them if
they are supported.

AC_CHECK_HEADERS already makes sure our config header contains a
HAVE_$FOO_H macro if a header was found. There is no need to
awkwardly set our own Automake conditionals and check for it all
over the place in the Automake files.

For some applications, like building a root filesystem for an embedded
device, it may be desireable to only build and install a subset of the
mtd-utils. This can be done throught the targets of the generated
Makefile and hand picking executables, however the jffsX and ubifs
utilities have external build dependencies that may not be needed.
This patch adds configure switches to disable building the jffsX and
ubifs utilities. Their respective build dependencies (zlib, lzo, uuid)
are only requested if the tools are being built.

Basically a user space port of the mtd torture test kernel module. In
addition to the block offset and count module parameters, the utility
supports a block stride and can restore the block contents after test.
In contrast to the kernel module, the torture test is implemented by
the libmtd mtd_toruture function and thus doesn't allow for similarly
fine grained options on diagnostics.

This patch adds a libmissing library to mtd-utils, containing
implementations of functionality found in glibc but typically
missing from embedded C libraries such as uclibc ot musl.
For now, the library only contains stub implementations of
the backtrace*() family of functions.

Add automake files for the test binaries. If configured to do so,
install the test binaries to libexec/mtd-utils and use autoconf to
fix the paths in the test scripts.

This patch is largely based on Richards original RFC.
The major differences to the RFC patch are:
- Add missing sumtools & mtdpart targets
- Fix name of mkfs.jffs2 target
- Add missing subdir-objects option for non-recursive make
- Move all automake options to configure.ac
- Add manpages to install target
- Make XATTR & LZO support configurable
- Install binaries to sbin directory like in the old build system
- Install flash_erase wrapper script
- Add files missing from distribution target
