gen{7,8}_pipeline: Always set ViewportXYClipTestEnable

For the following reasons, there is no behavioural change with this
commit: the ViewportXYClipTest function of the CLIP stage will continue
to be enabled outside of Meta (where disable_viewport is always false),
and the CLIP stage is turned off within Meta, so this function will
continue to be disabled in that case.

gen{7,8}_pipeline: Apply 3DPRIM_RECTLIST restrictions

According to 3D Primitives Overview in the Bspec, when the RECTLIST
primitive is in use, the CLIP stage should be disabled or set to have
a different Clip Mode, and Viewport Mapping must be disabled:

   Clipping: Must not require clipping or rely on the CLIP unit’s
   ClipTest logic to determine if clipping is required. Either the CLIP
   unit should be DISABLED, or the CLIP unit’s Clip Mode should be set
   to a value other than CLIPMODE_NORMAL.

   Viewport Mapping must be DISABLED (as is typical with the use of
   screen-space coordinates).

We swap out ::disable_viewport for ::use_rectlist, because we currently
always use the RECTLIST primitive when we disable viewport mapping, and
we'll likely continue to use this primitive.

The previous value of 18 was motivated by having drivers that want to expose
16 samplers but also use some additional samplers for internal use. Raising
the value even higher isn't going to hurt that case.

On the other hand, some drivers actually use PIPE_MAX_SAMPLERS as the number
of samplers they expose externally, so raising this number above 32 is fragile
(because several places in the code use bitfields, and tracking down and

mesa/st: Use _mesa_geometric_ functions appropriately

Change references to gl_framebuffer::Width, Height, MaxNumLayers
and Visual::samples to use the _mesa_geometric_ convenience functions
for those places where the geometry of the gl_framebuffer is needed.
This is in contrast to the geometry of the intersection of the
attachments of the gl_framebuffer.

This patch paves the way to enable GL_ARB_framebuffer_no_attachements
for all gallium drivers.

V.2:
 Remove itermeditate variable state.

i965/sf_state: Pull flat_enables out of prog_data

Previously, we were walking over the shader source to figure out which
inputs should be marked flat.  Now, we can just pull it out of prog_data.
This is needed for properly setting up 3DSTATE_SF/SBE for Vulkan and it
also means that it will get properly cached.

i965/fs: Make the repclear shader support either a uniform or a flat input

In the Vulkan driver we use a single flat input instead of a uniform
because setting up push constants is more disruptive to the pipeline than
setting up another vertex input.  This uses the number of uniforms as a key
to keep it working for the GL driver.

freedreno/ir3: insert extra move into phi

We had an implicit assumption that the phi src was assigned in it's
source (pred) block leading into the phi.  But this is not true with
NIR, so we can't just ignore the source block specified in the
nir_phi_src.  Insert an extra mov in the source block.  If it is not
required the CP pass will take it back out again.

Fixes:

freedreno/ir3: eliminate unnecessary absneg's

The frontend inserts (abs) and (neg)'s to convert between NIR boolean
(~0/0) and native boolean (1/0).  So we'd end up with things like:

   cmps.s.ge r1.x, ...
   absneg.s r1.x, (neg)r1.x
   absneg.s r1.x, (abs)r1.x
   sel.b32 r2.x, r0.x, r1.x, r0.y

The (neg) already gets collapsed due to the following (abs).  Now by
realizing that r1.x comes from a cmps.s instruction, we can drop the
(abs) as well.

docs/relnotes: document EGL_KHR_reusable_sync

egl: add EGL_KHR_reusable_sync to egl_dri

This patch enables an EGL extension, EGL_KHR_reusable_sync.
This new extension basically provides a way for multiple APIs or
threads to be excuted synchronously via a "reusable sync"
primitive shared by those threads/API calls.

This was implemented based on the specification at

https://www.khronos.org/registry/egl/extensions/KHR/EGL_KHR_reusable_sync.txt

v2
- use thread functions defined in C11/threads.h instead of
  using direct pthread calls
- make the timeout set with reference to CLOCK_MONOTONIC
- cleaned up the way expiration time is calculated
- (bug fix) in dri2_client_wait_sync, case EGL_SYNC_CL_EVENT_KHR
  has been added.
- (bug fix) in dri2_destroy_sync, return from cond_broadcast
  call is now stored in 'err' intead of 'ret' to prevent 'ret'
  from being reset to 'EGL_FALSE' even in successful case
- corrected minor syntax problems

v3
- dri2_egl_unref_sync now became 'void' type. No more error check
  is needed for this function call as a result.
- (bug fix) resolved issue with duplicated unlocking of display in
  eglClientWaitSync when type of sync is "EGL_KHR_REUSABLE_SYNC"
