With the addition of block device access to UBI volumes, we now
add a simple userspace tool to access the new ioctls.
Usage of this tool is as simple as it gets:
$ ubiblock --create /dev/ubi0_0
will create a new block device /dev/ubiblock0_0, and
$ ubiblock --remove /dev/ubi0_0
will remove the device.
Artem: slightly changed the header comment.

If the kernel doesn't know the max_beb_per1024 parameter in the attach
ioctl, but the call still succeeded ubi_attach and ubi_attach_mtd will
return 1 instead of 0.
In this case, the ubiattach command will detach the device and fail with
an error message.

The ioctl UBI_IOCATT has been extended with max_beb_per1024 parameter.
This parameter is used for adjusting the "maximum expected number of
bad blocks per 1024 blocks" for each mtd device.
The number of physical erase blocks (PEB) that UBI will reserve for bad
block handling is now:
whole_flash_chipset__PEB_number * max_beb_per1024 / 1024
This means that for a 4096 PEB NAND device with 3 MTD partitions:
mtd0: 512 PEB
mtd1: 1536 PEB
mtd2: 2048 PEB
the commands:
ubiattach -m 0 -d 0 -b 20 /dev/ubi_ctrl
ubiattach -m 1 -d 1 -b 20 /dev/ubi_ctrl
ubiattach -m 2 -d 2 -b 20 /dev/ubi_ctrl
will attach mtdx to UBIx and reserve:
80 PEB for bad block handling on UBI0
80 PEB for bad block handling on UBI1
80 PEB for bad block handling on UBI2
=> for the whole device, 240 PEB will be reserved for bad block
handling.
This may seems a waste of space, but as far as the bad blocks can appear
every where on a flash device, in the worst case scenario they can
all appear in one MTD partition.
So the maximum number of expected erase blocks given by the NAND
manufacturer should be reserve on each MTD partition.

Also remove the eraseblock type support, because kernel commit
a65a0eb6d198e058687a9214683bd1c418f20d39 set the dtype
parameter as obsolete.
Also adjust to some renames:
* 'UBI_PROP_DIRECT_WRITE' -> 'UBI_VOL_PROP_DIRECT_WRITE'
* 'struct ubi_set_prop_req' -> 'struct ubi_set_vol_prop_req'.
* 'UBI_IOCSETPROP' -> 'UBI_IOCSETVOLPROP'

The ubi-utils/src/ subdir is tossed as it just complicates things for no
real gain. The dictionary.h header is relocated to the ubi-utils/include/
since other headers in there need it.
The top level clean is replaced with a `find -delete` on objects, so it
might prune more than necessary, but many projects now do this sort of
thing and no one complained there.
A "mkdep" helper generates the actual rule, and the variables are used
with "foreach" to expand these automatically.
The tests subdir is updated only to reflect the ubi-utils source move.
Otherwise, it is left untouched as making that non-recursive isn't really
worth the effort.
While we're gutting things, also through in kbuild style output while
building to make things more legible.

Source files for libmtd, crc32, and fec are scattered throughout the
tree. Move them to a central location so they can be built into a
common "libmtd.a" library used by all mtd-utils programs.
This patch only renames/deletes files and does not change the content.
Also modify the build system and source code so that libmtd.a can be built
from a "common" location (lib/). Statically link all utilities at the top
level with libmtd.a . Minor changes to mkfs.ubifs to allow using the common
crc32 implementation.

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.

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.

Remove all old tools because I cannot maintain them and the original
authors do not seem to have time for this. Some of the tools do not
work properly, some are just vague and undocumented and seem to be
oriented to the environment of the IBM guys. Nevertheless, I'll
return the tool as is in the next commit, becouse they are still
useful.
This commit also adds a ubinize utility to generate UBI images.
