qemu-img: add the 'dd' subcommand
This patch adds a basic dd subcommand analogous to dd(1) to qemu-img.
For the start, this implements the bs, if, of and count options and requires
both if and of to be specified (no stdin/stdout if not specified) and doesn't
support tty, pipes, etc.
The image format must be specified with -O for the output if the raw format
is not the intended one.
Two tests are added to test qemu-img dd.
