Updated LGPL'd VGABIOS from SVN.

- Added initial version of the VGABIOS for Voodoo Banshee adapters.
- Several code optimizations to reduce binary size.
NOTE #1: Banshee version has no VBE support yet.
NOTE #2: Banshee binary uses PCI ID for Banshee PCI and Bochs temporarily
         modifies the PCI data for Voodoo3 and AGP models.
