We should use the off_t type instead of off64_t or u_int32_t as its
length is controlled by the WITHOUT_LARGEFILE flag.

There's a typo in lseek parameters order.
But, due to the value of SEEK_SET, this commit doesn't introduce a
change.

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.

Currently pcv macro print the error message only if we are not doing power cut
testing or if we have -v flag. But if we run without -v and an error happen
and the error code is not EROFS/EIO, pcv() does not print anything. This patch
makes it print the error message in that case as well.

Currently when we are doing UBIFS power cut emulation testing we assume that
EROFS is returned in case of an emulated power cut event. However, this is
not true and sometimes Linux returns EIO to user-space instead. Namely, this
happens when we are waiting for write-back to finish. Here is a call trace
form kernel 2.6.39-rc7:
Call Trace:
[<ffffffff810aaa77>] filemap_write_and_wait_range+0x78/0xb1
[<ffffffff8110f34d>] vfs_fsync_range+0x38/0xd3

'filemap_fdatawait_range()' returns hard-coded -EIO if a page write-back
happens with whatever error code.
Thus, this patch teaches integck to handle EIO when doing power cut emulation
testing.

This patch adds -m <mtdnum> option to integck and teaches integck to re-attach
the MTD device to UBI in case of an emulated power cut event. This is needed
for the new UBI power cut and unstable bits emulation infrastructure: when UBI
emulates a power cut the only way to recover form this is to re-attach the MTD
device.

Make the verify option -v work with power cut emulation option -e. We can
verify all operations except of writing to the file, because of write-back.
Indeed, even if we write successfully, the pages may still be in the page-cache
and if an emulated power cut happens they will be dropped, and our verification
will fail.
I am not 100% sure it is save to verify non-write operation in other FSes, but
only UBIFS has power cut emulation mode now, so we do not really care about
other FSes at this point.

All errors but write errors have corresponding CHECK(), so if something
gets wrong we fail. But in case of I/O errors we do not fail if an
unexpected error happens, which makes it difficult to trace issues.
Inject the errno checking to the pvc macro to make sure we fail if
errno is not EROFS.

Commit 1394a46213e8180e1233ca6d4811e7c77d49b1e0 was a good idea, but it
introduced a segfault - files can be unlinked and 'file->links' is NULL, it is
bad idea to unconditionally dereference it with 'file->links->name'. This patch
introduces a helper function which takes care of the situation with unlinked
files, plus it adds few assertions.

This is just a preparation - re-structure 'file_write()' to make one "success"

it delete the file errored in truncation, not only in write. Also, move

The test sometimes dies due to SIGBUS because a power cut event happens when
we are writing to an mmap()'ed area. SIGBUS is very difficult to ignore, so
fix the issue simply by avoiding doing 'mmap()' operations when in power cut
testing mode.

Do not check the file-system when we are in power cut mode. Currently
we still check the FS if we did not encounter any error, and the test
fails sometimes because meanwhile write-back encounters an error and
drops pages. Disable the checking so far. It should be enabled when
we implement the 'clean' flag for files.
