anv: Implement VK_EXT_external_memory_dma_buf

This is a modified version of the patch originally sent by Chad Versace.
The primary difference is that this version claims that OPQAUE_FD and
DMA_BUF are compatible handle types.

glsl: don't run intrastage array validation when the interface type is not an array

We validate that the interface block array type's definition matches.
However, previously, the function could be called if an non-array
interface block has different type definitions -for example, when the
precision qualifier differs in a GLSL ES shader, we would create two
different types-, and it would return invalid as both definitions are
non-arrays.

We fix this by specifying that at least one definition should be an

No statistically sigificant difference on the minetest trace I was looking
at (n=169), but the maximum FPS is up by .3%

broadcom/vc4: Simplify the relocation handling for index buffers.

Originally there was CL code for handling various relocations back when I
had relocs for the TSDA/TA buffers.  Now that the kernel handles those
entirely on its own, I can inline that code into the one place using it.

broadcom/vc4: Fix handling of GFXH-515 workaround with a start vertex count.

We failed to take the start into account for how many vertices to draw in
this round, so we would end up decrementing count below 0, which as an
unsigned number meant we would loop until the CLs soon ran out of space.

When I wrote the code I was thinking about how to use the previously
emitted shader state (no index bias baked into the elements) by emitting
up to 65535 and then only re-emitting with bias for the second wround, but
that doesn't work if the start is over 65535.  Instead, just delay
emitting shader state until we get into the drawarrays GFXH-515 loop and
always bake the bias in when we're doing the workaround.

broadcom/vc4: Fix the scaling factor for the GFXH-515 workaround.

For triangle strips, we step by max_verts - 2.

meson: use dep_thread instead of dependency('threads') in freedreno

They are the same thing, but this is more consistent with the rest of
