i965: Fix textureGather with RG32I/UI on Gen7.
According to the "Gather4 R32G32_FLOAT Bug" internal documentation
page, the R32G32_UINT and R32G32_SINT formats are affected by the
same bug as R32G32_FLOAT. Applying the same workarounds should be
viable - apparently the R32G32_FLOAT_LD format shouldn't corrupt
integer data which is NaN or other sketchy floating point values.
One irritating caveat is that, because it's a FLOAT format, the
alpha channel or any set to SCS_ONE return 0x3f8 (1.0) rather than
integer 1. So we need shader code to whack those channels to 1.

Original log for the i965 commit follows:
Some application, such as drm backend of weston, uses XRGB8888 config as
default. i965 doesn't provide this format, but before commit
65c8965d,
the drm platform of EGL takes ARGB8888 as XRGB8888. Now that commit
65c8965d makes EGL recognize format correctly so weston won't start
because it can't find XRGB8888. Add XRGB8888 format to i965 just as

gbm/drm: Pick the oldest available buffer in get_back_bo
Applications may query the back buffer age to efficiently perform
partial updates. Generally the application will keep a fixed length
damage history, and use this to calculate what needs to be redrawn
based on the age of the back buffer it's about to render to.
If presented with a buffer that has an age greater than the
length of the damage history, the application will likely have
to completely repaint the buffer.
Our current buffer selection strategy is to pick the first available
buffer without considering its age. If an application frequently
manages to fit within two buffers but occasionally requires a third,
this extra buffer will almost always be old enough to fall outside
of a reasonably long damage history, and require a full repaint.
This patch changes the buffer selection behaviour to prefer the oldest
available buffer.
By selecting the oldest available buffer, the application will likely
always be able to use its damage history, at a cost of having to
perform slightly more work every frame. This is an improvement if
the cost of a full repaint is heavy, and the surface damage between
frames is relatively small.
It should be noted that since we don't currently trim our queue in
any way, an application that briefly needs a large number of buffers
will continue to receive older buffers than it would if it only ever
needed two buffers.

egl/wayland: Avoid race conditions when on non-main thread
When EGL is used on some other thread than the thread that drives the
main wl_display queue, the Wayland EGL dri2 implementation is
vulnerable to a race condition related to display round trips and global
object advertisements.
The race that may happen is that after after a proxy is created, but
before the queue is set, events meant to be emitted via the yet to be
set queue may already have been queued on the wrong queue.
In order to make it possible to avoid this race, wayland 1.11
introduced new API that allows creating a proxy wrapper that may be used
as the factory proxy when creating new proxies via Wayland requests. The
queue of a proxy wrapper can be changed without effecting what queue
events emitted by the actual proxy will be queued on, while still
effecting what default queue proxies created from it will have.
By introducing a wl_display proxy wrapper and using this when performing
round trips (via wl_display_sync()) and retrieving the global objects (via
wl_display_get_registry()), the mentioned race condition is avoided.

radeonsi: restrict cube map derivative computations to the correct plane
As remarked by the comment in the original code, the old algorithm fails when
(tc + deriv) points at a different cube face. Instead, simply project the
derivative directly to the plane of the selected cube face.
The new code is based on exactly differentiating (using the chain rule)
the projection onto a plane corresponding to a fixed cube map face (which
is still selected in the usual way based on the texture coordinate itself).
The computations end up fairly involved, but we do save two reciprocal
computations.

gallium: add renderonly library
This a very lightweight library to add basic support for renderonly
GPUs. A kms gallium driver must specify how a renderonly_scanout
objects gets created. Also it must provide file handles to the used
kms device and the used gpu device.
This could look like:
struct renderonly ro = {
.create_for_resource = renderonly_create_gpu_import_for_resource,
.kms_fd = fd,
.gpu_fd = open("/dev/dri/renderD128", O_RDWR | O_CLOEXEC)
};
The renderonly_scanout object exits for two reasons:
- Do any special treatment for a scanout resource like importing the
GPU resource into the scanout hw.
- Make it easier for a gallium driver to detect if anything special
needs to be done in flush_resource(..) like a resolve to linear.
A GPU gallium driver which gets used as renderonly GPU needs to be
aware of the renderonly library.
This library will likely break android support and hopefully will get
replaced with a better solution based on gbm2.
Changes from V1 -> V2:
- reworked the lifecycle of renderonly object (suggested by Nicolai Hähnle)
- killed the midlayer (suggested by Thierry Reding)
- made the API more explicit regarding gpu and kms fd's

spirv: Handle patch decorations up-front
Once again, SPIR-V is insane... It allows you to place "patch"
decorations on structure members. Presumably, this is so that you can
do something such as
out struct S {
layout(location = 0) patch vec4 thing1;
layout(location = 0) vec4 thing2;
} str;
And have your I/O "nicely" organized. While this is a bit silly, it's
allowed and well-defined so whatever. Where it really gets interesting
is when you have an array of struct. SPIR-V says nothing about not
allowing you to have those qualifiers on the members of a struct that's
inside an array and GLSLang does this. Specifically, if you have
layout(location = 0) out patch struct S {
vec4 thing1;
vec4 thing2;
} str[2];
then GLSLang will place the "patch" decorations on the struct members.
This is ridiculous there is no way that having some of them be patch and
some not would be well-defined given that patch and non-patch outputs
are in effectively different storage classes. This commit moves around
the way we handle the "patch" decoration so that we can detect even the
crazy cases and handle them.
