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.
