[Mesa-dev] Meta path for gen8 stencil

[Topi Pohjolainen]

I have the corresponding bits also for gen6-7, but there is a little
work left in that front. Passes all the relevant piglit tests on bdw.

Topi Pohjolainen (13):
  i965: Allow stencil to be used for sampling and as render target
  i965/wm: Surface state overrides for configuring w-tiled as y-tiled
  i965/gen8: Use helper variables for surface parameters
  i965/gen8: Allow stencil buffers to be configured as single sampled
  i965/gen8: Surface state overriding for stencil
  i965: Extend brw_get_rb_for_first_slice() for specified level/layer
  i965/blorp: Expose coordinate scissoring and mirroring
  meta: Merge compiling and linking of blit program
  meta: Refactor binding of renderbuffer as texture image
  meta: Refactor configuration of renderbuffer sampling
  meta: Refactor state save/restore for framebuffer texture blits
  i965/meta: Stencil blits
  i965/fb: Use meta path for stencil blits
