Before, we were trusting in the hardware to take the intersection
of the viewport clip with the drawing rectangle. Unfortunately,
3DSTATE_DRAWING_RECTANGLE is fairly expensive because it implicitly
does a full pipeline stall. If we're a bit more careful with our
viewport clipping, we can just re-emit it once at context creation
time.

lower_blend_equation_advanced().
This requires passing an extra argument to the lowering pass because
the KHR_blend_equation_advanced specification doesn't seem to define
any mechanism for the implementation to determine at compile-time
whether coherent blending can ever be used (not even an "#extension
KHR_blend_equation_advanced_coherent" directive seems to be required
in the shader source AFAICT).
In the long run we'll probably want to do state-dependent recompiles
based on the value of ctx->Color.BlendCoherent, but right now there
would be no benefit from that because the only driver that supports
coherent framebuffer fetch is i965 on SKL+ hardware, which are unable
to support the non-coherent path for the moment because of texture
layout issues, so framebuffer fetch coherency is always enabled for
them.

This reverts two bogus and seemingly useless changes from the commits
referenced below, which broke KHR_blend_equation_advanced (and
EXT_shader_framebuffer_fetch_non_coherent which wasn't exposed yet)
for any kind of render target surface that would cause the
get_isl_surf() call in brw_emit_surface_state() to do anything useful
(notice how the result of get_isl_surf() is completely ignored by the
caller right now), as was the case while using those extensions with
1D array or 3D framebuffers in particular.

Switch over to use the _DrawVAO for all the array type draws.
The _DrawVAO needs to be set before we enter _mesa_update_state, so move
setting the draw method in front of the first call to _mesa_update_state
which is in turn called from the *validate*Draw* calls. Using the
gl_vertex_array_object::_Enabled bitmask, gl_vertex_program_state::_VPMode

To get equivalent information than get_vp_mode(), track the vertex
processing mode in a per context variable at
gl_vertex_program_state::_VPMode.
This aims to replace get_vp_mode() as seen in the vbo module.
But instead of the get_vp_mode() implementation which only gives correct
answers past calling _mesa_update_state() this context variable is
immediately tracked when the vertex processing state is modified. The
correctness of this value is asserted on state validation.
With this in place we should be able to untangle the dependency with
varying_vp_inputs and state invalidation.

The setTexBuffer2 hook from GLX is used to implement glxBindTexImageEXT
which has tighter restrictions than just "it's shared". In particular,
it says that any rendering to the image while it is bound causes the
contents to become undefined.
The GLX_EXT_texture_from_pixmap extension provides us with an acquire
and release in the form of glXBindTexImageEXT and glXReleaseTexImageEXT.
The extension spec says,
"Rendering to the drawable while it is bound to a texture will leave
the contents of the texture in an undefined state. However, no
synchronization between rendering and texturing is done by GLX. It
is the application's responsibility to implement any synchronization
required."
From the EGL 1.4 spec for eglBindTexImage:
"After eglBindTexImage is called, the specified surface is no longer
available for reading or writing. Any read operation, such as
glReadPixels or eglCopyBuffers, which reads values from any of the
surface’s color buffers or ancillary buffers will produce
indeterminate results. In addition, draw operations that are done
to the surface before its color buffer is released from the texture
produce indeterminate results
In other words, between the bind and release calls, we effectively own
those pixels and can assume, so long as we don't crash, that no one else
is reading from/writing to the surface. The GLX and EGL implementations
call the setTexBuffer2 and releaseTexBuffer function pointers that the
driver can hook.
In theory, this means that, between BindTexImage and ReleaseTexImage, we
own the pixels and it should be safe to track aux usage so we
can avoid redundant resolves so long as we start off with the right
assumption at the start of the bind/release pair.
In practice, however, X11 has slightly different expectations. It's
expected that the server may be drawing to the image at the same time as
the compositor is texturing from it. In that case, the worst expected
outcome should be tearing or partial rendering and not random corruption
like we see when rendering races with scanout with CCS. Fortunately,
the GEM rules about texture/render dependencies save us here. If X11
submits work to write to a pixmap after the compositor has submitted
work to texture from it, GEM inserts a dependency between the compositor
and X11. If X11 is using a high-priority context, this will cause the
compositor to get a temporarily boosted priority while the batch from
X11 is waiting on it. This means that we will never have an actual race
between X11 and the compositor so no corruption can happen.
Unfortunately, however, this means that X11 will likely be rendering to it
between the compositor's BindTexImage and ReleaseTexImage calls. If we
want to avoid strange issues, we need to be a bit careful about
resolves because we can't really transition it away from the "default"
aux usage. The only case where this would practically be a problem is
with image_load_store where we have to do a full resolve in order to use
the image via the data port. Even there it would only be a problem if
batches were split such that X11's rendering happens between the resolve
and the use of it as a storage image. However, the chances of this
happening are very slim so we just emit a warning and hope for the best.
This commit adds a new helper intel_miptree_finish_external which resets
all aux state to whatever ISL says is the right worst-case "default" for
the given modifier. It feels a little awkward to call it "finish"
because it's actually an acquire from the perspective of the driver, but
it matches the semantics of the other prepare/finish functions. This
new helper gets called in intelSetTexBuffer2 instead of make_shareable.
We also add an intelReleaseTexBuffer (we passed NULL to releaseTexBuffer
before) and call intel_miptree_prepare_external in it. This probably
does nothing most of the time but it means that the prepare/finish calls
are properly matched.

The old code made a new miptree that referenced the same BO as the
renderbuffer and just trusted in the memory aliasing to work. There are
only two ways in which the new miptree is liable to differ from the one
in the renderbuffer and neither of them matter:
1) It may have a different target. The only targets that we can ever
see in intelSetTexBuffer2 are GL_TEXTURE_2D and GL_TEXTURE_RECTANGLE
and the difference between the two doesn't matter as far as the
miptree is concerned; genX(update_sampler_state) only looks at the
gl_texture_object and not the miptree when determining whether or
not to use normalized coordinates.
2) It may have a very slightly different format. Again, this doesn't
matter because we've supported texture views for quite some time so
we always look at the gl_texture_object format instead of the
miptree format for hardware setup anyway.
On the other hand, because we were recreating the miptree, we were using
intel_miptree_create_for_bo which doesn't understand modifiers. We
really want this function to work without doing a resolve so long as you
have modifiers so we need to fix that.

By default, 3DSTATE_CONSTANT_* Constant Buffer 0 is relative to dynamic
state base address. This makes it unusable for pushing UBOs.
There is a bit in the INSTPM register (or CS_DEBUG_MODE2 on Skylake)
which controls whether buffer 0 is relative to dynamic state base
address, or simply a normal pointer. Setting that gives us full
flexibility. This lets us push up to 4 UBO ranges.
We can't currently write this on Haswell and earlier, and will need
to update the kernel command parser, and then do the whole version
checking song and dance. We also need a brand new kernel that supports
context isolation - on older kernels, newly created contexts inherit
register state from whatever happened to be running. So, setting this
would have catastrophic impact on other drivers such as libva, Beignet,
or older Mesa.
See commit 8ec5a4e4a4a32f4de351c5fc2bf0eb615b6eef1b where we did this

The previous commit reworked the checks intel_from_planar() to check the
right individual cases for regular/planar/aux buffers, and do size
checks in all cases.
Unfortunately, the aux size check was broken, and required the aux
surface to be allocated with the correct aux stride, but full image
height (!).
As the ISL aux surface is not recorded in the DRIimage, we cannot easily
access it to check. Instead, store the aux size from when we do have the
ISL surface to hand, and check against that later when we go to access
the aux surface.
