llvmpipe: Tighten check for alpha-only formats

The AoS version of ld_build_blend_factor was assuming that if the first
channel was alpha, there were no rgb components.

Fixes glean/blendFunc on System z.  No piglit regressions on x86_64.
The shortcut is still used in tests like spec/ARB_framebuffer_object/
fbo-alpha.

radeonsi: Implement DMA blit

This code is a slightly modified version of evergreen_dma_blit (and
evergreen_dma_copy as well as evergreen_dma_copy_tile).
It would be nice to share some of the code in the long term.

I have reused some "cik"-prefixed functions that also return the right
value for SI. I am not sure if they should be renamed.

v2: Marek> removed gfx.flush in si_dma_copy_tile

mesa: fix software fallback for generating mipmaps for 3D textures

It didn't use the driver-provided src/dstRowStride at all.
This was broken for the cases when stride != width*bpp.

gallium/u_gen_mipmap: remove the software fallback

The last changes to it are from 2008 and 2009.
It doesn't support most texture formats and some texture targets.
Nobody can possibly be using this.

st/mesa: drop the lowering of quad strips to triangle strips

This fallback to triangle strips is silly and should be done in drivers
if they need it.

This should fix the case when quad strips are used with flatshading that is
enabled by the "flat" GLSL varying modifier. It also fixes primitive restart
for quad strips.

This fixes piglit:

nvc0/ir: move sample id to second source arg to fix sampler2DMS

The nvc0 texfetch instruction expects the sample id to be in the second
source (usually used for the offset) rather than as part of the texture
coordinate.

This fixes all the sampler2DMS/Array tests on nvc0.
