This improves tiled texture performance of OA on my 945 from 25.3fps
to 29.0fps, whereas untiled is 28.2fps, by avoiding stalls for fence
register changes.
This moves the logic for how to align pitches, heights, and sizes of
objects to one central location. Fixes rendering with texture tiling
on i915. Note that current libdrm is required for the change for
I915_TILING_NONE pitch alignment.
The weirdness that led to the bumping of pitch for those 512/1024
pixels is that in taking a 2x2 subspan or bilinear filtering we'd end
up hitting the same channel in 2 different pages, leading to lower
performance. With tiling, that doesn't occur, so we don't need to
waste the memory.
there is no need for these to be persistent since we flush the CS
at the end of the blit, and we don't reuse these buffers at all.
on my r600 the Wine DX9 test suite doesn't crash at least anymore.

Move transfer creation and mapping to the "scene" object, and out of
the rasterizer. The rasterizer operates on already-mapped
framebuffers only, and no longer needs a screen or context pointer.
The scene object has access to a pipe_context, and this reorg prepares
for moving transfer functionality from the screen to the context.
This fixes the sw fallback for GL_SELECT picking modes.

implements if/else/endif constructs and lays down the code for looping
and others. we create a conditional execution mask which decides which
of the four inputs are enabled for any store. it's used only if an
execution mask is present, otherwise we go through a direct store.
DMA buffers are often remapped many times for singel cs. To reduce number of
mapping calls ending to kernel dma buffers are mapped when allocated and unmapped
when full or in cs flush. This makes indifual mapping calls in other parts of
code simple increment/decrement reference count which is faster than entering
kernel.
This improves Anholt's openarena benchmark from 36 fps to 44 fps.
