"3d" -> "virgl" as 3d is a rather broad term.
Hopefully a bit less confusing.

dma_memory_map() may map only a part of the request. Happens if the
request can't be mapped in one go, for example due to a iommu creating
a linear dma mapping for scattered physical pages. Should that be the
case virtio-gpu must call dma_memory_map() again with the remaining
range instead of simply throwing an error.
Note that this change implies the number of iov entries may differ from
the number of mapping entries sent by the guest. Therefore the iov_len
bookkeeping needs some updates too, we have to explicitly pass around
the iov length now.

In the past, virtio-gpu set NULL as the surface for the secondary
consoles to hide its window. The distinction is now handled in
ui/console and the display backends and virtio-gpu does no longer
have to do that.

Add a base class that is common to virtio-gpu and vhost-user-gpu
devices.
The VirtIOGPUBase base class provides common functionalities necessary
for both virtio-gpu and vhost-user-gpu:
- common configuration (max-outputs, initial resolution, flags)
- virtio device initialization, including queue setup
- device pre-conditions checks (iommu)
- migration blocker
- virtio device callbacks
- hooking up to qemu display subsystem
- a few common helper functions to reset the device, retrieve display
informations
- a class callback to unblock the rendering (for GL updates)
What is left to the virtio-gpu subdevice to take care of, in short,
are all the virtio queues handling, command processing and migration.

disas, standard-headers, linux-headers and libdecnumber are imported

Due to a kernel bug we can never increase the size of capability
set 1, so introduce a new capability set in parallel, old userspace
will continue to use the old set, new userspace will start using
the new one when it detects a fixed kernel.
v2: don't use a define from virglrenderer, just probe it.
v3: fix compilation when virglrenderer disabled
v4: fix style warning, just use ?: op instead.
