This is the other half of Keith's draw/flush patch.
There are now 5 flush flags to control what's flushed (post-xform vertex
cache, prim cache, vbuf, etc).
The gears slow-down in this part of the patch was due to the cull stage not
getting invoked. It was unconditional before, but is now gated by 'need_det'.
But it also needs to be gated by draw->rasterizer->cull_mode. Gears uses
back-face culling.

Remove all dependencies on vertex_info, except for draw_vbuf.
Drawing stages now strictly operate on post-transformed vertices and don't
know anything about hw vertices.
Use vertex program output info for two-side/flat/etc stages.
Temporarily disable vbuf module in softpipe driver.

This sub-struct collects the incoming user-provided data/pointers in one place.
Ex: draw->mapped_vbuffer becomes draw->user.vbuffer, etc.

Need to set the slot's bit in draw->vcache.referenced even when there was a
cache hit since flushing the primitive buffer will have cleared the bitfield
but not the cache's vertex indexes.
Fixes a bug found when drawing long triangle fans but could be hit by other
prim types as well.
An alternate fix would be to call draw_vertex_cache_invalidate() from
draw_vertex_cache_unreference().

Also, assert that index is not too large before indexing array.

Build a buffer of contigous vertices and indices at the backend of our
software transformation/clipping path. This will become the mechanism
for emitting buffers of vertices to rasterization hardware.
This is similar to but not the same as the post-transform vertex cache.
In particular, these vertices are subject to clipping, culling, poly offset,
etc. The vertices emitted will all be used by hardware.
TODOs include the actual transformation to hardware vertex formats, moving
this out of softpipe to somewhere more useful and allowing >1 primitive to
share the generated VB.
