net: copy socket ioctl code to net/socket.h
This makes an identical copy of the socket compat_ioctl code from fs/compat_ioctl.c to net/socket.c, as a preparation for moving the functionality in a way that can be easily reviewed. The code is hidden inside of #if 0 and gets activated in the patch that will make it work. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S. Miller <davem@davemloft.net>
