DOS MBRs might contain an extended partition that holds several logical
partitions. Add these to the partitions of the block device.

The code used to ineffectively take the end of the last partition as guess
for the disk size. Better use the end of the partition that has its end
rearmost.
Also return an unsigned type instead of int as the result is always
non-negative.

The NT disk Signature is a unique 32-bit value in the MBR allowing
to identify a MSDOS partitioned disk. The signature can be used to
specify the Linux rootfs.
This patch adds support for the NT disk Signature in the form of a
device parameter which can both be read and written.

The disk partitions use blockdevice functions, so add the corresponding
depends on BLOCK.

Some drivers use blk->ops->read/write. This bypasses the caching block
layer and was never intended like this. The upper API to the block layer
is the cdev layer. This patch adds block_read and block_write functions
and uses them where appropriate.

form linux 3.8
so you can have part by num or name
not by GUID as this is a non human reading name
