brooks 3e372bcfc3 Add a request structure and make the implementation use it. ... This allows compatibility translation to take place on the stack (md_ioctl is too big) and is more suitable as a public interface within the kernel than the kern_ioctl interface. Except for the initialization of the md_req from the md_ioctl (including detection of kernel md_file pointers) and the updating of the md_ioctl prior to return, this is a mechanical replacment of md_ioctl and mdio with md_req and mdr.
