to an mtd device.

Remove the 'dev_major' and 'dev_minor' fields from the volume

Now there is a new option '-p' (or '--dev-path') that can be used to pass path
to a MTD device node.

struct ubi_attach_request now has additional field 'dev' that can contain path
to the MTD device node in the filesystem. Also there are two new functions that
are able to handle path to the MTD device node:
ubi_attach() - attach MTD device by number or by path
ubi_detach() - detach MTD device by path
ubi_attach() works like ubi_attach_mtd() when it is passed empty req->dev,
otherwise it looks up correct MTD device number based on the given device node
path.

We fixed the sequence numbers bug, which is quite serious.

This commit fixes a stupid an nasty bug. When we flash an UBI image,
we do not change its sequence numbers. But when we format the rest
of the PEBs (beyond the flashed image), we use a random (or specified
via cmdline) sequence number. As a result, we have a broken flash
format and UBI refuses it, because half of it has one sequence number,
another half has a different one.
What we have to do instead, we have to substitute image's sequence
number with ours.

Add current time to the PID to improve the pseudo-random number
generator seeding. Also, use 'rand()' instead of 'random()', because
'srand()' is for 'rand()'.

args.image_seq is of type uint32_t and was initialized to -1 which
becomes 0xFFFFFFFF in this case. Later the value -1 was used as a flag
that args.image_seq should be replaced with a randomized value.
With the option --image-seq (-Q) a user could provide any sequence
number at will.
But when the user provided sequence number was 0xFFFFFFFF this was
understood effectivly as -1 and got overridden by a randomized
sequence number.
So this patch change the programm flow to respect the principle of
least surprise and never use a randomized sequence number when the
user provide one at own will.

UBI image sequence number which we store in EC headers is 32 bits,
not 64-bits. I was confused when noticed that the 'image_seq'
variable had type 'unsigned long long'. Turn it into a 'uint32_t'
type.

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.

It's already about 2 years since the "-d" option was declared
deprecated. UBI utils have printed a warning about this. Now
it is time to kill this option completely.
The affected utilities are ubimkvol, ubirmvol and ubiupdatevol.
Their versions are also increased.

When ubiformat prints something like
ubiformat: bad eraseblocks: 1400
it looks like there are 1400 bad eraseblock, although there is
only one with number 1400. Fix this but turning the print into
ubiformat: 1 bad eraseblock found, numbers: 1400

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.

This patch contains changes similar to the ones in the previous
patch.
Also, it changes all invocations of memset and makes sure
the argument is 0, not '\0', because memset expects int,
not char.
