This device implements the IM120417002 colors shield v1.1 for Arduino
(which relies on the DM163 8x3-channel led driving logic) and features
a simple display of an 8x8 RGB matrix. The columns of the matrix are
driven by the DM163 and the rows are driven externally.

This API manages objects (in this iteration,
dmabuf fds) that can be shared along different
virtio devices, associated to a UUID.
The API allows the different devices to add,
remove and/or retrieve the objects by simply
invoking the public functions that reside in the
virtio-dmabuf file.
For vhost backends, the API stores the pointer
to the backend holding the object.

When using --disable-virglrenderer, QEMU still creates
hw-display-virtio-gpu-gl.so
hw-display-virtio-vga-gl.so
hw-display-virtio-gpu-pci-gl.so
but when these are loaded, they provide no functionality as the code
which registers types is not compiled in. Funtionally this is
relatively harmless, because QEMU is fine loading a module with no
types.
This is rather confusing for users and OS distro maintainers though,
as they think they have the GL functionality built, but in fact the
module they are looking at provides nothing of value.
The root cause is the use of 'when/if_true' rules when adding sources
to the module source set. If all the rules evaluate to false, then we
have declared the module, but not added anything to it. We need to
put declaration of the entire module inside a condition based on
existance of the 3rd party library deps that are mandatory.

NB:
We do not expect any functional change in any ACPI tables with this
change. It's only a refactoring.
NB2:
Some targets (or1k) do not support acpi and CONFIG_ACPI is off for them.
However, modules are reused between all architectures so CONFIG_ACPI is
on. For those architectures, dummy stub function definitions help to
resolve symbols. This change uses more of these and so it adds a couple
of dummy stub definitions so that symbols for those can be resolved.

Add helper functions to create a dmabuf for a resource and mmap it.
Also, introduce the fields blob and blob_size so that these helpers
can start to use them but the full picture will emerge only after
adding create_blob API in patch 8 of this series.
To be able to create a dmabuf using the udmabuf driver, Qemu needs
to be lauched with the memfd memory backend like this:
qemu-system-x86_64 -m 8192m -object memory-backend-memfd,id=mem1,size=8192M
-machine memory-backend=mem1
