This introduces a new feature to the MTD command line utilities that
allows MTD devices to be referenced by name instead of device node. For
example this looks like:
> # Display info for the MTD device with name "data"
> mtdinfo mtd:data
> # Copy file to MTD device with name "data"
> flashcp /my/file mtd:data
This follows the syntax supported by the kernel which allows MTD
device's to be mounted by name[1].
Add the function mtd_find_dev_node() that accepts an MTD "identifier"
and returns the MTD's device node. The function accepts a string
starting with "mtd:" which it treats as the MTD's name. It then attempts
to search for the MTD, and if found maps it back to the /dev/mtdX device
node. If the string does not start with "mtd:", then assume it's the old
style and refers directly to a MTD device node.
The function is then hooked into existing tools like flashcp, mtdinfo,
flash_unlock, etc. To load in the new MTD parsing code in a consistent
way across programs.

This is a convenience function for end users. In some situations it's
easier to reference MTD device's by their name then by MTD number, as
the name may be more reliable if device partitioning is dynamic or for
porting between systems.

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.

libubi.h includes ubi-media.h which was made private in the kernel a
long time ago. There are users of libubi.h, e.g. swupdate, which have to
have ubi-media.h available at build time with this inclusion.
However, libubi.h uses only one symbol from ubi-media.h. Define that symbol
in the header to enable using libubi.h without installing ubi-media.h.
Make up for the transitive symbol use in ubiformat.c by including ubi-media.h.

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.

The prompt() function is intended to query a yes/no reply from a command
line user by reading in an entire line of text using getline() and checking
the first character. If the line is empty, a default value is returned.
First of all, this patch replaces the usage of getline() with fgets() to
avoid compilation problems on some smaller C libraries, like klibc, that
do not have a getline() implementation. Since we now have a static line
length, this may break some build setups that input lengthy giberish
instead of 'y' or 'n'.
Second, this patch fixes a more severe bug in prompt(), replacing a 'while'
keyword with the 'if' that was most likely intended. In the old version, if
getline() reported an error, it would print an error message inside a while
loop, immediately followed by a break and then march on and process the
erroneous input instead of using the default value as printed to stdout.

Update both header files to add support for flag specifying whether to
skip the CRC check for static UBI volumes.
Taken from the kernel headers.
Some users of static UBI volumes implement their own integrity check,
thus making the volume CRC check done at open time useless. For
instance, this is the case when one use the ubiblock + dm-verity +
squashfs combination, where dm-verity already checks integrity of the
block device but this time at the block granularity instead of verifying
the whole volume.
Skipping this test drastically improves the boot-time.

A common pattern in command line processing is having a usage()
function that prints out how to use the command line options and
then terminates.
The function is typically used inside a switch block for command
line options like `-h' or unknown options. In a lot of places, the
break keyword is omitted, because the function exits anyway. However,
this triggers gcc warnings about implicit fall-through.
Rather than adding a phony "/* fall-through */" this patch flags the
usage() style function with a gcc attribute, indicating that they do
not return and removes further superfluous break statements.

The documentation of libmtd_open says, if it returns NULL and errno is
zero, MTD is not present. However, the current version always returns
a libmtd_t object. The function internally checks, if it can access the
MTD sysfs files and, if not, sets a flag to use the procfs fallback.
This patch adds an additional check to libmtd_open, to test if the
MTD procfs file can be read and fails with errno cleared if it does
not exist.
Furhtermore, mtd_get_info is documented to fail with errno set to ENODEV
if MTD is not present. First of all, this was broken in the original
version. It was implemented to specification for the sysfs code path,
but if MTD is not present, that won't be executed, because of the flag
set by libmtd_open. This makes the check not only redundant, but masks
an actual error (the sysfs paths suddenly not being readable anymore).
The legacy path that was used if the sysfs files are not avaible fails
with ENOENT if it cannot read the procfs file. With the above changes
in addition, we don't have a libmtd_t object if neither sysfs nor
procfs is readable, so this error status no longer makes sense.
This patch removes the documentation on the ENODEV errno, and
makes sure that mtd_get_info always returns with apropriate errno
on failure.

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.

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

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".
