mesa/st: enable ARB_fragment_layer_viewport

If multiple viewports are supported, that implies the presence of a GS
and layered rendering, so we can enable ARB_fragment_layer_viewport as
well.

st/xa: Don't close the drm fd on failure v2

If XA fails to initialize with pipe_loader enabled, the pipe_loader's
cleanup function will close the drm file descriptor. That's pretty bad
because the file descriptor will probably be the X server driver's only
connection to drm. Temporarily solve this by dup()'ing the file descriptor
before handing it over to the pipe loader.

This fixes freedesktop.org bugzilla bug #80645.

glsl: fix duplicated layout qualifier detection for GS

This patch fixes the duplicated layout qualifier detection

Also it makes the detection code more legible by defining

radeon/llvm: Allocate space for kernel metadata operands

Previously, we were assuming that kernel metadata nodes only had 1 operand.

Kernels which have attributes can have more than 1, e.g.:
!0 = metadata !{void (i32 addrspace(1)*)* @testKernel, metadata !1}
!1 = metadata !{metadata !"work_group_size_hint", i32 4, i32 1, i32 1}

Attempting to get the kernel without the correct number of attributes led
to memory corruption and luxrays crashing out.

Fixes the cl/program/execute/attributes.cl piglit test.

nv50: disable dedicated ubo upload method

The hardware allows multiple simultaneous renders with the same
memory-backed constbufs but with each invocation having different
values. However in order for that to work, the data has to be streamed
in via the right constbuf slot. We weren't doing that for UBOs.
