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.

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

This patch fixes the return status of the mtd_torture function
in libmtd.
The torture test function is currently only used by the ubiformat

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.

This is done to allow creating images suitable for IMA directory
appraisal. IMA creates a hash for directories and attaches this
hash to the directory itself as an extended attribute. Among other
things the inode numbers of the files are hashed. So, to create
a valid hash in the UBIFS image the evmctl tool needs to know
the inode numbers which the files in the UBIFS image will have.
evmctl will read the inode numbers from the user.image-inode-number
extended attribute. Since extended attributes are inodes themselves
the inode numbers for the generated image will change when the
extended attributes change, so to generate a correctly hashed
UBIFS image, both evmctl and mkfs.ubifs must be run twice:
1) execute evmctl to iterate over the directory tree. This will
create the security.ima and security.evm extended attributes.
The existence of the attributes makes sure that subsequent
calls to mkfs.ubifs will use the same inode numbers. evmctl
will use the inode numbers from the host filesystem in this
step which makes the resulting image unusable
2) execute mkfs.ubifs -a. This will create the user.image-inode-number
extended attributes on files/directories added to the image.
3) execture evmctl again. This time evmctl will pick the inode
numbers from the user.image-inode-number extended attribute
instead of the ones from the host filesystem
4) execute mkfs.ubifs again. This will create the correct image.
The now existing user.image-inode-number extended attributes
are ignored and not added to the image.

Add new --lock/--unlock flags, so we can do either with the same binary.
This will prepare for the addition of other features, so we don't have
to keep duplicating the same binary via #include "flash_unlock.c".
The defaults still work as expected: flash_unlock will default to
REQUEST_UNLOCK, and flash_lock will default to REQUEST_LOCK.
Eventually, we might deprecate one of the two (flash_unlock, probably),
so we only have to ship one flash_{un,}lock binary.
