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.

This patch enhances the flash_unlock utility to be able to do
unlocking for specified blocks range.
This patch also fixes calculation of 'length' as in previous patch.
Say there are 240 blocks present in the device. Then:
offset starts from: 0x0
and full size of device: 0x1E00000
doing: 240 * 0x20000 gives -> 0x1E00000
But last block address should be 0x1DE0000 (which spans for 0x20000
bytes, adding up to size of 0x1E00000)

This patch fixes the 'length' calculation.
Making it:
+ mtdLockInfo.length = (num_sectors - 1) * mtdInfo.erasesize;
Rather:
- mtdLockInfo.length = num_sectors * mtdInfo.erasesize;
Say there are 240 blocks present in the device. Then:
offset starts from: 0x0

But last block address should be 0x1DE0000 (which spans for 0x20000

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,

Nandwrite tries to use lseek() when failing to write on a page. lseek()
will fail when used on the standard input so nandwrite fails. This code
replaces lseek with a buffer.
When the data is read, it is put in a buffer (filebuf). This buffer is
reset at each block boundary. So a "seek" just means reading from the
beginning of the buffer. writebuf and oobreadbuf are now just pointers
to locations in filebuf.

With the device table one can add /dev entries to the root file system
image. The device table file contains among others the fields minor,
start, increment and count. If there is an entry with minor=0 start=0
increment=32 and count=4 the mkfs.ubifs makes 128 device entries, with
minor numbers from 0 to 127. The correct version makes 4 entries with
minor number 0,32,64,96.
/dev/mtd c 640 0 0 90 0 0 2 7
This gives 14 devices /dev/mtdXX instead of 7 devices.
Due to this error mtd_debug info /dev/mtd3 delivers the information of
/dev/mtd1 instead of.

if the image was written on top of an older image. Support

Fixed broken behavior in case of write failure. More specifically:
- Only try to mark a block bad if the errors are EIO. Other errors
will abort the tool.
- Also abort the tool if the marking fails instead of ignoring it.

If the file contains only a few bytes in the last page and the

(readlen < meminfo.oobsize).

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.
