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:

vc4 i915 svga virgl swr panfrost iris lima kmsro

The glMemoryBarrier() function makes shader memory stores ordered with
respect to things specified by the given bits. Until now, st/mesa has
ignored GL_TEXTURE_UPDATE_BARRIER_BIT and GL_BUFFER_UPDATE_BARRIER_BIT,
saying that drivers should implicitly perform the needed flushing.
This seems like a pretty big assumption to make. Instead, this commit
opts to translate them to new PIPE_BARRIER bits, and adjusts existing
drivers to continue ignoring them (preserving the current behavior).
The i965 driver performs actions on these memory barriers. Shader
memory stores go through a "data cache" which is separate from the
render cache and other read caches (like the texture cache). All
memory barriers need to flush the data cache (to ensure shader memory
stores are visible), and possibly invalidate read caches (to ensure
stale data is no longer visible). The driver implicitly flushes for
most caches, but not for data cache, since ARB_shader_image_load_store
introduced MemoryBarrier() precisely to order these explicitly.
I would like to follow i965's approach in iris, flushing the data cache
on any MemoryBarrier() call, so I need st/mesa to actually call the
pipe->memory_barrier() callback.
Fixes KHR-GL45.shader_image_load_store.advanced-sync-textureUpdate
and Piglit's spec/arb_shader_image_load_store/host-mem-barrier on
the iris driver.
Roland said this looks reasonable to him.

There was an issue recently caused by the system header being included
by mistake, so let's just get rid of this include path and always

This just renames this as we want to add an shm handle which
isn't really drm related.

Resources created with modifiers are treated as scanout because there is
no way for applications to specify the usage (though that capability may
be useful to have in the future). Currently all the resources created by
applications with modifiers are for scanout, so make sure they have bind
flags set accordingly.
This is necessary in order to properly export buffers for such resources
so that they can be shared with scanout hardware.

Resources created for scanout but without modifiers need to be treated
as pitch-linear. This is because applications that don't use modifiers
to create resources must be assumed to not understand modifiers and in
turn won't be able to create a DRM framebuffer and passing along which
modifiers were picked by the implementation.

Tegra K1 and later use a GPU that can be driven by the Nouveau driver.
But the GPU is a pure render node and has no display engine, hence the
scanout needs to happen on the Tegra display hardware. The GPU and the
display engine each have a separate DRM device node exposed by the
kernel.
To make the setup appear as a single device, this driver instantiates
a Nouveau screen with each instance of a Tegra screen and forwards GPU
requests to the Nouveau screen. For purposes of scanout it will import
buffers created on the GPU into the display driver. Handles that
userspace requests are those of the display driver so that they can be
used to create framebuffers.
This has been tested with some GBM test programs, as well as kmscube and
weston. All of those run without modifications, but I'm sure there is a
lot that can be improved.
