Matt Borgerson c9df1d1047 nv2a: Replace some non-critical assertions with debug macros 
In the event these features are utilized, execution may still continue,
albeit with the likely possibility graphical problems of varying degree.
This patch replaces hard assertions with debug print statements when
configured to do so.

current screen resolution set up by firmware.

Stas'M dd1248a563 nv2a: Set PCI class id and subsystem id to match hardware 
This patch sets the class id, subsystem id, and subsystem vendor id
in the PCI device header to match what the NV2A hardware advertises.

This resolves an issue with PCI device enumeration failing to detect and load
the driver for the NV2A device in some operating systems, namely ReactOS
version 0.2.5-xbox (custom build), which depend on these fields being
programmed correctly.

Matt Borgerson 47452495c0 nv2a: Fix NV097_SET_VERTEX_DATA2S scaling 
Vertex attribute values provided via NV097_SET_VERTEX_DATA2S are
apparently two 16-bit signed integers, packed into 32 bits, which are
then to be directly mapped to floating point values in the range
[-32768.0, 32767.0].

Halo:CE uses this format to provide texture (u,v) coordinates for
render-to-texture techniques, including weapon scope, dynamic shadows,
and radar beacon--all of which are now working as expected with this
patch.

Matt 316967c441 nv2a FIFO Refactoring (#76) 
* Port espes's fifo work to the split up nv2a code

This patch ports over the following commits from the XQEMU 1.x tree
(available via tag archive-xqemu-1.x) to the refactored nv2a code:

- 4d9107e8 (HEAD -> xbox, upstream/xbox) Merge branch 'fix-fifo' into xbox
- c33f4ab2 cleanups
- d3f83d93 cleanups
- faca5dd0 fix
- 7c62d7c1 fixes
- 8ad239b0 wip
- 45ed3c31 wip
- c006d5e8 wip

However, in its current form, this patch causes some regressions and
needs further investigation.

* nv2a: basic pattern object
