The mtdoob and mtdraw device don't clean up correctly.
Added a private data element to hold allocated memory.
Fix remove of mtdoob and mtdraw device.

When unaligned writes are used, typically doing a cp file /dev/mtdraw0.foo,
the alignement correction code was incorrectly handling such cases, and
didn't return the expected number of written bytes.
This was tested on a 528 block size.

Add a device to read and write to MTD data and oob
(/dev/mtdraw<N>).
The device is constrained in a separate source file, so that
further improvement of commands (such as nandwrite) could
make it useless, and easy to remove.
