Currently mtd-utils on 32bit systems fail on devices >2GiB due to off_t being
a signed 32bit type. Add AC_SYS_LARGEFILE to make off_t a 64bit type.
Adding AC_SYS_LARGEFILE results in _FILE_OFFSET_BITS being defined to 64
in include/config.h. To let this have an effect we must make sure that
include/config.h is included before all other includes which is
archieved by adding its inclusion to CPPFLAGS.

- Remove "install tests" configure option, we already have an option
whether to build tests or not. Don't try to work around autotools
semantics that people building the package expect.
- Fix the installation path by propperly defining it and using the
correct name for the libexec path.

The "need_getrandom" check and result is used only for the "ubihealthd".
This tool is very important to have it around at run-time, while the
corresponding "mkfs.ubifs" tool is still optional (think about offline
generated ubifs images).
Since compiling "mkfs.ubifs" adds more dependencies (various shared
libraries), buildsystems for embedded devices will add these shared
libraries to the root filesystem even if "mkfs.ubifs" isn't used or
installed.
Thus, handling both tools independently makes sense. The previous behavior
is kept, e.g. if UBIFS support is enabled, it enables "ubihealthd" as well.

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

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).

mtd_debug: Remove a duplicate if case. MTD_CAP_NANDFLASH has only one
flag set (MTD_WRITEABLE). Directly below, we had a check for
MTD_WRITEABLE in the else branch which can't possible ever have
triggered. Checking for MTD_WRITEABLE in addition to the CAP constants
was probably not intended anyway, given the check for the individual
flags if all else fails.
integck: We already established that "r" is less than the number of
elements in the list, so the loop condition doesn't need to check
if w is NULL in addition. At least this way, the compiler "gets"
that w cannot be NULL below and doesn't issue warnings.

This patch attempts to cleanly seperate configure switches,
dependency checking and generating of output files inside
the autoconf configure.ac file.
Also, instead of aborting immediately if a dependency is missing,
the configure script now completes dependency checking and then
lists ALL dependencies that are missing for the selected build
options. In addtion, suggestions on how to disable some features
that require the missing dependencies are printed out.

On 32bit systems (e.g. ARM) the size of off_t can be 4 byte and the size of loff_t 8 byte.
This causes compiler warnings like the following:
flash_erase.c: In function 'show_progress':
flash_erase.c:56:22: warning: format '%llx' expects argument of type 'long long unsigned int', but argument 3 has type 'off_t {aka long int}' [-Wformat=]
bareverbose(!quiet, "\rErasing %d Kibyte @ %"PRIxoff_t" -- %2i %% complete ",
and an output like this:
~# flash_erase /dev/mtd2 0 1
Erasing 64 Kibyte @ 6400000000 -- 0 % complete
~#
Since the size of off_t and loff_t can differ from each other, the
printf format specifier should be determined separately for both.
Further the format specifiers should be based directly on the size of the
particular data type.

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.

Compiling for x86_64 generates a lot of warning because the PRIxoff_t and
PRIdoff_t are not properly defined, which comes from the missing
SIZEOF_LONG definition.
Use the autotools to generate a config.h header, include this header from
common.h and ask autoheader to generate the SIZEOF_LONG and SIZEOF_LOFF_T
definitions.
Use these new definitions to assign the proper descriptors to PRIxoff_t
and PRIdoff_t.

The programs mkfs.jffs2 and mkfs.ubifs include those two headers if
WITHOUT_XATTR is not defined. Up to now, this macro is only defined
if the configure script is run with --without-xattr. If the headers
are not present on a system and the configure script is run without
special flags set, the build fails.
This patch adds a check for the presence of those headers and disables
the feature if one of the headers is missing.

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
