Several tools are simply not checking return code of functions marked
with 'warn_unused_result'.
Provide wrappers for the read/write functions to avoid patching old
code and providing proper error handling.
Fix the remaining ones (calls to fgets() and system()).

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.

Historically, the mtd-utils and ubi-utils were seperate packages. The
ubi-utils were at some point merged into the mtd-utils. They first
appeared in the release tar-ball in version 1.1.0 in their own
sub-hirarchy with their own buildsystem, readme, documentation, etc.
A lot of the duplicated stuff got centralized/removed over time.
This patch further cleans up the directory hirarchy duplication by
moving common libraries from the ubi-utils/ into the central lib/
and include/ directories in the top directory of the mtd-utils package.
This includes:
- libuib.a & libubigen.a used by the ubi utilities
- libscan.a currently only used by ubiformat
- libiniparser.a used by ubinize

This patch moves the remaining 3 functions from ubiutils-common.{c,h}
into libmtd common.{c,h}.
The functions are only generic utility functions that other mtd-utils
programs may also find usefull and every program that uses libubi links
against libmtd anyway so there is no real reason for keeping around a
seperate ubiutils-common with only generic helper functions.

When a program does sophisticated enough command line processing
(i.e. getopt), make sure it responds to -V and --version.
When a program prints a version string, make sure it uses the
common_print_version macro to print out its name, that it is part
of mtd-utils and the mtd-utils version from the build system in a
fashion similar to common program packages like the GNU coreutils.
When a program responds to -V/--version or -h/--help, make sure it
reports success exit status.

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

This patch removes the old feature-removal-schedule.txt file from
mtd-utils, mostly for reasons similar to the ones that lead to the
decision of removing the feature-removal-schedule.txt from the kernel.
Removing features by itself is rather problematic as there is no
simple way of estimating whether something is being used widley or
not at all. Thus, consensus usually tends towards not removing
features at all.
Even if there is a file anouncing feature removal, users in large
won't read this file _if_ it is even included in distribution
packages. People working on mtd-uils would end up removing features
that _they_ find useless and users would start complaining once
their setups break after they install a new version of mtd-utils.
In conclusion, once introduced, features should not be removed to
begin with and this file is entirely usless.

Some of the programs in the mtd-utils used to be seperate packages that
were at some point merged into mtd-utils. As a result, some subdirectories
contain their own README and COPYING files with copies of the GPLv2
license text.
Since those programs are now part of mtd-utils that contains a copy of the
GPLv2 in the file COPYING in the package root directory, those extra files
can be removed, as there is no need for distributing an extra copy of the
license text for each individual program in the bundle.

Building packages for distributions is typically something highly
distribution specific. While there are widely used package formats
like RPM, implementing a de-facto standard, the build process,
list of files actually packaged, list of required dependencies,
package grouping, package versioning, etc... is still _very_
distribution specific. In fact, this spec file completely fails to
address some of these points.
Actual RPM based distributions out there currently use their own,
distribution specific, RPM spec files that were possibly _based_ on
this one at some point (judging from similar descriptions).
The spec file _may_ have worked at some point, but it definitely doesn't
work with the new build system and there is no real reason to fix it
(which, by definition, isn't possible for the reasons above) and drag it
along for another decade or two.

The function _tries_ to support short reads but doesn't adjust the
pointer into the buffer. If a short read happens, we scrambles the
flash contents. Interrupted reads aren't handled. Short or
interrupted writes aren't handled at all. Either a write succeeds
writing the entire buffer or the function gives up.
During an attempt at fixing it, it was discovered, that no mtd-utils
program uses this function. Furthermore, its highly specific nature
makes it more of a "feature looking for use case".

This _entire_ file is dead code. The download packages on the FTP
server contain it all the way back to mtd-utils 1.0, but it isn't
built in any of them. The git history (which dates back to 2006)
contains no instance where that file was ever used in a build process.
A quick look at various distribution packages didn't reveal any that
contained a jffs-dump utilty. There have been no major changes to this
file since the initial commit. It won't even compile as it doesn't have
a PROGRAM_NAME defined required by common.h at least since 2010.
At this point, it can be safeley assumed that nobody will miss this.
They had at least 10 years to do something about it.

The mtd_get_dev_info1 function reads (among other things) name and type
string into coresponding struct mtd_dev_info fields.
The struct mtd_dev_info has the string fields marked const, requiring
them to be cast to non-const version during initialization.
This cast was previously omitted from the dev_read_data calls,
triggering warnings during compilation.

Errors may happen, it's e.g. easy on embedded devices to run out of space
when dumping big partitions. This patch adds a helper function for
writing. It deals with partial writes and just returns 0 on success or
error number.
The old code didn't check for errors at all which could result in
incomplete dumps without exiting with an error.

This fix was initialially part of a patch submitted by Carsten Schlote
in January 2009. It didn't get merged back then because of coding style
issues and a proposed buffer size change guessed by shotgun debugging.
I was unable to reproduce the claimed segfaults in the compression
function that lead to the proposed buffer size change. Valgrind did
not issue any errors or warnings about the code in question either,
so I didn't include the proposed buffer size change.
The original patch also added a call to lzo_init(), which (according
to LZO documentation & source code) does not actually perform any
initialization, but only checks at runtime that the data type sizes and
endianness of the library code match those in the caller code and
should be unnecessary.
Other fixes from the original patch have already been added over
the years.

In commit ca7a5eda221d("integck.c: Fix buffer overflow in save_file")
we started including header <bits/stdio_lim.h>.
But with musl C library, we get following build error
integck.c:37:28: fatal error: bits/stdio_lim.h: No such file or directory
#include <bits/stdio_lim.h>
^
compilation terminated.
make[2]: *** [integck] Error 1
Header <bits/stdio_lim.h> is not available in musl C library. However
<stdio.h> has all definition that <bits/stdio_lim.h> supposed to be
providing. Moreover <bits/stdio_lim.h> shouldn't be included directly
instead we should be using <stdio.h>.
Since we already include <stdio.h> and in case of uClibc or glibc
<bits/stdio_lim.h> gets included internally, we can safely remove it.
This build issue is found by Buildroot autobuilder

The kernel refuses to read more data from a MTD device than the device
size. However, mtd_debug does not check the amount of data read as
returned by read(2) and assumes the requested amount is always read when
there is no error. Reading 8M data from a 4M flash chip results in 8M

This patch fixes the return status of the mtd_torture function
in libmtd.
The torture test function is currently only used by the ubiformat
utility to check if a block is bad after a write fails (blocks are
marked bad if the function returns an error status). However, the
way the function was written, it ALWAYS returns an error value
regardless of whether it failed or not.
