Usage/version information should go to stdout when it is expected behavior
(i.e. the user requested it explicitly). This info should go to stderr
only when the usage info is being shown as a result of incorrect options.

Instead of using strtol and Co directly, use our share simple_strtoX()
helpers. This is just a cleanup.

Shrink the data size a little by declaring addresses of constant strings
instead of pointers to it.
Also slip in static & const on long_options missing them.

Make sure all the utils define PROGRAM_NAME and do so at the start of
the file so that sub-headers may assume it exists.

And all the stuff specific to ubi-utils is in ubi-utils/include/ubiutils-common.h

Let's consistently use 'mtd_num' name for MTD device number. At the
moment some code uses 'mtd_num', other 'dev_num'. Harmonize that.

UBI now supports the image sequence number feature which
prevents UBI from mistakingly accepting half-written images,
if the image was written on top of an older image. Support
this feature in ubinize and make it pick a random
number for the UBI image sequence number.

Not-so-old linux kernel like 2.6.29 do already have "/sys/class/mtd/mtdX"
directories, while very old kernels do not. But in 2.6.29 these
directories do not contain any information.
Anyway, the logic in libmtd which checked whether the system
supports sysfs was broken, because it assumed that old systems
do not even have "/sys/class/mtd/" directory.
Fix this problem by checking for "/sys/class/mtd/mtdX/name". If this
is present - the system really has sysfs support.
This patch also adds an extra print to libmtd.
