i965: Don't reallocate push constant URB space on new VS programs.
The gen7_urb atom depends on CACHE_NEW_VS_PROG and CACHE_NEW_GS_PROG,
causing gen7_upload_urb() to be called when switching to a new VS
program.
In addition to partitioning the URB space between the VS and GS,
gen7_upload_urb() also allocated space for VS and PS push constants.
Unfortunately, this meant that whenever CACHE_NEW_VS was flagged, we'd
reallocate the space for the PS push constants. According to the BSpec,
after sending 3DSTATE_PUSH_CONSTANT_ALLOC_PS, we must reprogram
3DSTATE_CONSTANT_PS prior to the next 3DPRIMITIVE.
Since our URB allocation for push constants is entirely static, it makes
sense to split it out into its own atom that only subscribes to
BRW_NEW_CONTEXT. This avoids reallocating the space and trashing
constants.
Fixes a rendering artifact in Extreme Tuxracer, where instead of a snow
trail, you'd get a bright red streak (affectionately known as the
"bloody penguin bug").
This also explains why adding VS-related dirty bits to gen7_ps_state
made the problem disappear: it made 3DSTATE_CONSTANT_PS be emitted after
every 3DSTATE_PUSH_CONSTANT_ALLOC_PS packet.

this patch adds an internal wayland_drm_buffer_has_alpha() function.
It's important to get the internal format for an EGLImage right so that
if a GL texture is later created from the image then the GL driver will
know if it should sample the alpha from the texture or flatten it to
a constant of 1.0.
This avoids needing fragment program workarounds in wayland compositors

Note: strictly speaking this patch isn't necessary, since the maximum

the Outputs array is MAX_PROGRAM_OUTPUTS (64), so it's impossible to
have enough varyings to overflow the array. However it seems prudent

draw/softpipe: add clip vertex support. (v2)
softpipe always clipped using the position vector, however for unclipped
vertices it stored the position in window coordinates, however when position
and clipping are separated, we need to store the clip-space position and
the clip-space vertex clip, so we can interpolate both separately.
This means we have to take the clip space position and store it to use later.
This allows softpipe to pass all the clip-vertex piglit tests.
v2: fix llvm draw regression, the structure being passed into llvm needed
updating, remove some hardcoded ints that should have been enums while there.

i965: Replace references to stencil region size with buffer size
It is unwise to use a stencil region's size to determine its
renderbuffer's size, because at region creation we fudge the width and
height to accomodate interleaved rows. (See the comment for MESA_FORMAT_S8
in intel_miptree_create()). Most users of stencil_region->{width,height}
should be converted to use stencil_rb->{Width,Height}.
We have already done the replacement in several locations. This patch
continues the replacement in {brw,gen7}_emit_depthbuffer(). To make those
functions look consistent, I've also done the equivalent replacement for
the depth buffer.
