ubiformat segfaults like this:
ubiformat: mtd0 (NAND), size 134217728 bytes (128.0 MiB), 16384 eraseblocks of 16384 bytes (16.0 KiB), min. I/O size 512 bytes
libscan: scanning eraseblock 8191 -- 100 % complete
ubiformat: 8190 eraseblocks have valid erase counter, mean value is 9
ubiformat: 2 eraseblocks are supposedly empty
ubiformat: warning!: VID header and data offsets on flash are 512 and 1024, which is different to calculated offsets 256 and 512
ubiformat: use new offsets 512 and 1024? (yes/no) no
Segmentation fault
The reason is that volume table size is calculated for 256/512
layout, and when user chooses 512/1024 - it is not re-calculated
which leads to segfault in 'ubigen_write_layout_vol()'.
This patch also fixes the message - in the above output new
offsets are 256/512, not 512/1024.
Also, this patch adds explicit printing of the selected
positions.

Remove the fd field from the mtd information data structure,
because libmtd does not really know the device node file name,
and serves only as a place to save the descriptor. The callers
should find a better place.
This patch improves code readability and prepares for further
changes.

Building out of tree currently fails with ubi-utils because make gets
confused and can't figure out the vpathed .c files. Using VPATH rather
than vpath seems to work around it.

Some compilers (like gcc-3.3) don't support all the newer -W flags that we
are using. So import the compiler check found in the kernel and test each
flag we add. The := is important so we only do the compiler tests once
per `make` rather than every time we compile a file.

the compress size parameter in lzo is defined in the header file as lzo_uint.
This looks very much like uint32_t, I know, but is defined as unsigned long.
So on 64bit LE systems we zero some bytes near by and on BE systems we
get a size of zero.

The 2GiB limit is at erase block 8192. In mtd_is_bad() the computation
for the MEMGETBADBLOCK ioctl() looks like the following:
| seek = eb * mtd->eb_size;
with both eb and mtd->eb_size being a signed int results in seek being a
signed result.
The _FILE_OFFSET_BITS=64 define is required to switch off_t from 32bit
to 64bit an 32bit systems. This is required in order to keep using
lseek() as lseek64 on 32bit system. Without this change lseek() in
mtd_read() is called with a 32bit value with most significat bit set and
the kernel performs a sign extension for the 64bit value which is used
in the mtd layer.
The last change also changes the size of the parameter which is passed
to the MEMGETBADBLOCK ioctl() from 32 to 64bit. The counter part in
kernel is also defined as loff_t which is of type __kernel_loff_t and
this is "long long". So this must have been broken for a while unless I
missed something.

The execution of

'strcmp(args.img, "-")' will segfault.

I got some reports from people who use make-3.80 that mtd-utils wasn't
building correctly the first time. Turns out that older versions of make
misbehave with pattern rules and full paths. So I've tweaked the code a
little to work with make-3.80 and make-3.81 (the latest release).
Also, I added a small optimization to avoid running `mkdir` when building
in-tree.

With older mtd-utils, creating a directory in the root worked fine. With
current git, the parent dir search algo breaks this.
For example, just take the current git tree, build it up, and then run:
$ ./mkfs.jffs2 -d . -D device_table.txt -o /dev/null
mkfs.jffs2: skipping device_table entry '/dev': no parent directory!
mkfs.jffs2: skipping device_table entry '/dev/mem': no parent directory!
...
Doing `mkdir ./dev` first works around the issue, but where's the fun in
that.

gcc-4.3.x introduces a number of new warnings (and we use -Werror) for
things like not checking scanf return values and not using explicit
formatting. Finally, it caught that we were overflowing our own buffer
in unubi.c, so increate the variable size as we want to declare and
clear PATH_MAX + 1, then use only PATH_MAX of the variable.

Let's have the "new ubi-utils" makefile handle CFLAGS like the other
