When Mesa is compiled for gallium-xlib using e.g.
./configure --enable-glx=gallium-xlib --disable-dri --disable-gbm
-disable-egl
and is used by an X server (usually remotely via SSH X11 forwarding)
that does not support MIT-SHM such as XMing or MobaXterm, OpenGL
clients report error messages such as
Xlib: extension "MIT-SHM" missing on display "localhost:11.0".
ad infinitum.
The reason is that the code in src/gallium/winsys/sw/xlib uses
MIT-SHM without checking for its existence, unlike the code
in src/glx/drisw_glx.c and src/mesa/drivers/x11/xm_api.c.
I copied the same check using XQueryExtension, and tested with
glxgears on MobaXterm.

When a texture is still bound as an image and the context it was bound in
is destroyed but not the texture, then the texture will still hold the
resource and will not be freed when it is finally destroyed. Hence, release
these references when the context is destroyed.

This patch implements the free Midgard shader toolchain: the assembler,
the disassembler, and the NIR-based compiler. The assembler is a
standalone inaccessible Python script for reference purposes. The
disassembler and the compiler are implemented in C, accessible via the
standalone `midgard_compiler` binary. Later patches will use these
interfaces from the driver for online compilation.

Commit 8b626a22b2 introduced a new
pipe_image_view::shader_access field, indicating the access mode
specified in the shader. st/mesa's built-in PBO download shader
creates a write-only image buffer, so we should flag it as such.
Nobody uses this field yet (Iris will), so we don't need to backport
