TGSI's FBFETCH instruction currently only supports reading from a single
render target, but NIR intrinsics can support multiple render targets.
radeonsi can only support fetching from RT 0, but other drivers may be
able to support fetching from any render target.
To express this, this patch renames PIPE_CAP_TGSI_FS_FBFETCH to simply
PIPE_CAP_FBFETCH, and converts it from a boolean "is FBFETCH supported?"
to an integer number of render targets which can be fetched.

The _LEVELS assumes that the max is always power of two. For V3D 4.2, we
can support up to 7680 non-power-of-two MSAA textures, which will let X11
support dual 4k displays on newer hardware.

Adds a new cap to allow drivers to expose higher shading language
versions in GLES contexts, to avoid having to report an artificially
low version for the benefit of GL contexts.
The motivation is to expose EXT_gpu_shader5 even though a driver may
not support all the features needed for the corresponding GL extension
(ARB_gpu_shader5).

but only have up to 124 varying-interpolated input components. We add a
new cap to express this cleanly. For most drivers, this will have the

Iris would like to use compact arrays for tesslevels and clip/cull

since it'll be necessary for GL_ARB_gl_spirv support, but it's not ready

Add a new cap that indicates whether the drivers supports
enabling/disabling the conversion from linear space to sRGB

whether the driver can switcht between a linear and and a sRGB surface

Intel's blending hardware does not properly return 1.0 for destination
alpha for RGBX formats; it requires the factors to be overridden to
either zero or one. Broadcom vc4 and v3d also could use this override.
While overriding these factors is safe in general, Nouveau and Radeon
would prefer not to. Their blending hardware already returns correct
values for RGB/RGBX formats, and would like to avoid the resulting
per-buffer blending and independent blend factors (rgb != a) since it
can cause additional overhead.
I considered simply handling this in the driver, but it's not as nice.
pipe_blend_state doesn't have any format information, so we'd need the
hardware blend state to depend on both pipe_blend_state and
pipe_framebuffer_state. Furthermore, Intel GPUs don't have a native
RGBX_SNORM format, so I avoid exposing one, which makes Gallium fall
back to RGBA_SNORM. The pipe_surfaces we get in the driver have an RGBA
format, making it impossible to tell that there shouldn't be an alpha
channel. One could argue that st not handling it in that case is a bug.
To work around this, we'd have to expose RGBX pipe formats, mapped to
RGBA hardware formats, and add format swizzling special cases. All
doable, but it ends up being more code than I'd like.
st_atom_blend already has access to the right information and it's
trivial to accomplish there, so we just add a cap bit and do that.

Gallium historically has treated pipeline statistics queries as a single
query, PIPE_QUERY_PIPELINE_STATISTICS, which returns a block of 11
values. This was originally patterned after the D3D1x API. Much later,
Brian introduced an OpenGL extension that exposed these counters - but
it exposes 11 separate queries, each of which returns a single value.
Today, st/mesa simply queries all 11 values, and returns a single value.
While pipeline statistics counters aren't typically performance
critical, this is still not a great fit. A D3D1x->GL translator might
request all 11 counters by creating 11 separate GL queries...which
Gallium would map to reads of all 11 values each time, resulting in a
total 121 counter reads. That's not ideal.
This patch adds a new cap, PIPE_CAP_QUERY_PIPELINE_STATISTICS_SINGLE,
and corresponding query type PIPE_QUERY_PIPELINE_STATISTICS_SINGLE.
When calling create_query(), q->index should be set to one of the
PIPE_STAT_QUERY_* enums to select a counter. Unlike the block query,
this returns the value in pipe_query_result::u64 (as it's a single
value) instead of the pipe_query_data_pipeline_statistics group.
We update st/mesa to expose ARB_pipeline_statistics_query if either
capability is set, preferring the new SINGLE variant when available.
Thanks to Roland, Ilia, and Marek for helping me sort this out.

Some hardware can do PIPE_TEX_WRAP_MIRROR_REPEAT but not
PIPE_TEX_WRAP_MIRROR_CLAMP and PIPE_TEX_WRAP_MIRROR_CLAMP_TO_BORDER.
Drivers for such hardware would like to advertise support for
ARB_texture_mirror_clamp_to_edge but not EXT_texture_mirror_clamp.
This commit adds a new PIPE_CAP_TEXTURE_MIRROR_CLAMP_TO_EDGE bit,
changes the extension enable to be based on that, and enables it
in all upstream drivers which supported PIPE_CAP_TEXTURE_MIRROR_CLAMP
(so they continue supporting this mode).
