Other modules can register and unregister ioctl handlers to extend the ioctls known by the Linuxulator. A recent application is the vmware port. The Linuxulator itself uses the new interface to register its handlers as well. Handlers for the following types of ioctls have been defined: cdrom console (=keyboard and VT handling) socket sound termio All ioctl related defines and declarations have been moved to a new file (linux_ioctl.h), except for the pluggable ioctl handler interface definition. While there, cleanup linux.h some more. linux.h and linux_ioctl.[ch] have been made to conform to style(9) as much as possible. Inspired and reviewed by: Vladimir N. Silyaev
