"flash_erase" fails on nand flash with JFFS2 that has OOB size greater than
32 bytes. "flash_erase" uses "MEMGETOOSEL" to determine OOB size. This ioctl
call is obsolete and returns error if OOB size is more than 32 bytes.
This patch fixes this issue by using "mtd_write" to update clean-marker
instead of mtd_oob_write. This fix is based on the discussion:

To be independent on the size of off_t the format specifier determined of
common.h should be used instead of PRIu64.

Add correct casting for filestat.st_size in flashcp.c. While the
interim status updates had correct casting from commit 08b243, the
final update was not.

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()).

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

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
file containing the flash data at the start.

The _BSD_SOURCE define has been deprecated for a while now. Instead,
code should be defining _DEFAULT_SOURCE. By defining both, it'll work
with both new & old versions warning-free.

filestat.st_size type is off_t.
For some paltforms, off_t can be 32 or 64bit but there is no C99 format specifier for off_t.
The best way to print it with printf is to cast it to long long and print with %llu

* There is no code modification in this commit, only moving
* the files to proper place.
The user tools looks a little messy as we place almost
the all tools in the root directory of mtd-utils. To make
it more clear, I propose to introduce the following structure
for our source code.
mtd-utils/
|-- lib
|-- include
|-- misc-utils
|-- jffsX-utils
|-- nand-utils
|-- nor-utils
|-- ubi-utils
|-- ubifs-utils
`-- tests
