i965: fix polygon stipple when rendering to FBO

The polygon stipple pattern, like the viewport and the
polygon face orientation, must be inverted on the i965
when rendering to a FBO (which itself has an inverted pixel
coordinate system compared to raw Mesa).

In addition, the polygon stipple offset, which orients
the stipple to the window system, disappears when rendering
to an FBO (because the window system offset doesn't apply,
and there's no associated FBO offset).

With these fixes, the conform triangle and polygon stipple
tests pass when rendering to texture.

was not.  This caused a conform failure when rendering to texture with

vbo: yet tighter still usage of FLUSH_NEED_CURRENT

Previous change broke redbook/polys and probably others.  I'm fairly
sure that drivers like r300 don't need to touch
ctx->Driver.NeedVertices, but this code is incredibly fragile and I'm
not confident about removing it from there.  Hopefully this gets
things working again.

This variable is being used in the r300 driver to trigger a flush under
circumstances unrelated to the use in the vbo module.  Tighten up the
checks in vbo so as to avoid conflict with r300.
