mesa/st: rewrite src var when lowering tex_src_plane

The assign_extra_samplers() adds the needed extra samplers but they need
to be used in the nir_tex_instr.
Otherwise the plane information is simply lost and all nir_tex_instr use the
same sampler.
Here's an example of the bug:

NIR before st_nir_lower_tex_src_plane:
vec1 32 ssa_8 = load_const (0x00000000 /* 0.000000 */)
vec4 32 ssa_9 = tex ssa_0 (texture_deref), ssa_0 (sampler_deref), ssa_5 (coord), ssa_8 (plane)
vec1 32 ssa_10 = load_const (0x00000001 /* 0.000000 */)
vec4 32 ssa_11 = tex ssa_0 (texture_deref), ssa_0 (sampler_deref), ssa_5 (coord), ssa_10 (plane)

After:

vec4 32 ssa_9 = tex ssa_0 (texture_deref), ssa_0 (sampler_deref), ssa_5 (coord)
vec4 32 ssa_11 = tex ssa_0 (texture_deref), ssa_0 (sampler_deref), ssa_5 (coord)

This fixes the following piglit test for radeonsi + NIR:
  - ext_image_dma_buf_import-sample_nv12

gallium: switch boolean -> bool at the interface definitions

This is a relatively minimal change to adjust all the gallium interfaces
to use bool instead of boolean. I tried to avoid making unrelated
changes inside of drivers to flip boolean -> bool to reduce the risk of
regressions (the compiler will much more easily allow "dirty" values
inside a char-based boolean than a C99 _Bool).

This has been build-tested on amd64 with:

iris: Support storage images that have matching typed formats for reads

Even if we don't directly support typed reads on a format, we can often
translate them to a reasonable matching format.  Advertise those too.

iris: Stop advertising MSAA storage images by mistake

st_extensions.c sets const->MaxImageSamples (GL_MAX_IMAGE_SAMPLES) by
looping over [16, 15, .. 1x] MSAA modes, and RGBA/BGRA/ARGB/ABGR 8888
color formats, calling pipe->is_format_supported() for each, with
the usage set to PIPE_BIND_SHADER_IMAGE.  If any are supported, it
selects that number of samples.

We were checking if sample_count <= 1, which meant that we were getting
a value of 1x MSAA, rather than the expected 0x (feature doesn't exist).

But, only on Icelake because Gen11 adds support for typed read messages
for R8G8B8A8_UNORM.  The lack of typed read messages for these formats
was tricking the check on Gen9 to say no correctly.  This caused some
Icelake conformance failures, because we don't implement this feature.

Just check for sample_count == 0 instead.

egl: Only expose 565 pbuffer configs if X can export them as DRI3 images

Glamor in xorg-server 1.20 cannot expose 16bpp pixmaps when running in
the usual 24bpp mode.  This meant our 565 pbuffer configs would
ultimately fail to create a backing pixmap, leading to crashes.

To hack around this, make a 16bpp pixmap and try and export it.
If it works, expose the configs.  Otherwise, just skip them.

This also disables them on DRI2.  These configs were only added to pass
conformance requirements, and I doubt anybody cares about testing out
565 pbuffer visuals on DRI2-only drivers.

egl: Make the 565 pbuffer-only config single buffered.

In commit dacb11a585face5ca179c34cfc588a71a425c1e0, Eric found the first
matching 565 pbuffer config, and stopped.  Our double-buffered configs
come first in the list, so we added that, making a pbuffer-only config
that claimed to be double buffered.  This doesn't make sense, since
pixmaps/pbuffers are fundamentally not double buffered.

When using that config, every call to eglCreatePbufferSurface would fail
with EGL_BAD_MATCH.  The call chain looks like this:

   - eglCreatePbufferSurface
   - dri3_create_pbuffer_surface
   - dri3_create_surface
   - dri2_get_dri_config

which eventually does:

   const bool double_buffer = surface_type == EGL_WINDOW_BIT;

and then fails to find a matching config, because it ends up looking
for a single-buffered config - and there aren't any.

To fix this, make the 565 pbuffer config single-buffered.  This fixes
at least 51 dEQP-EGL.* tests.
