Changes for new vbo-building module.
- Removed all the old immediate, array and display list code.
- Remove references to the old array_cache module.
- Added a _tnl_draw_prims() entrypoint.
- Added a simplified data import facility for converting
non-floating point data as required.
Checkpoint commit - trivial/tri works.
