Preparing for supporting graphic drivers on Linux.

1. Make the code multiple-device aware (even if I can't
   test it, it is better to have it designed like this since now).

2. Added the beginning of the /dev/{graphics,opengl}, /dev/gfx
   drivers.

3. Renamed newport.c to cons_newport.c.  This is just the console
   rendering code.  Will put the more complex virtualizing, context
   switching code for the newport on newport.c

4. streamable.c is supposed to have all of the stream devices that
   we need for IRIX emulation (not much there just now): shmiq, gfx and
   keyboard and mouse plugins.

More tomorrow, now it is time to sleep :-)
