#1 display-list support

[michael_f]

Adds support for rendering (but not creating)
native-format dlists.
For a crappy example of a dlist, see
http://www.rafb.net/paste/results/o3uK7c54.html
For better examples, see metroid model viewer thingy
(metroid models contain raw dlists)
FIXME: dlists should be thrown at the fifo using DMA,
not the CPU
Dlist builder tool to follow.
