input.h: Use int_val for freelook
cl_input.c: Use freelook macro instead of in_mlook.state
in_svgalib.c: freelook support and whitespace
in_win.c: whitespace and minor optimization in mouse support
in_x11.c: freelook support
vid_ggi.c: joystick support and minor opt in mouse support
vid_sdl.c: joystick support, freelook support, minor mouse opt, spaces->tabs
support are built with joy_null.c. To create a joystick driver for a new
system, take a look at joystick.h and joy_null.c for the driver
interface. I'd like to see a Windows driver using this interface, it would
probably simplify in_win.c greatly.
