We can use MaybeUninit instead of heap allocation to ensure that our

every message in the fs device and this saves us some unnecessary small
heap allocations.
Switch Reader::read_obj to use this method so that we don't have
multiple implementations of the same thing. This also fixes some
unsoundness in read_obj where we were creating a `&mut [u8]` out of

Protected VMs require all virtio data to be bounced through a memory
window shared between the host and the guest. Although this can be
achieved by forcing the guest to use swiotlb bouncing for all DMA
transfers, the recent introduction of "Restricted DMA" in Linux allows
these buffers to be sized and allocated on a per-device basis.
Remove the 'swiotlb=force' option when '--protected-vm' is set in favour
of describing a reserved memory region to be used as the swiotlb buffer
for all virtio-pci devices, adjustable via the new '--swiotlb' option.

The conversion code for KVM <-> hypervisor representation of the Local
APIC state used the unsafe mem::transmute() function to view an array of
i8 as u8 instead for use with the Rust endian conversion functions.
Casting between integer types of the same size with `as` is defined in
Rust as a "no-op" (the bitwise representation is preserved), just like
in C, so transmuting at the slice level is not needed. These can instead
be written as simple loops to avoid the unsafe code.
To ensure this does not regress code quality, I have compared the code
generated for the x86-64 release build. The kvm_lapic_state to
LapicState conversion compiles to identical code, and the reverse
compiles to slightly different code (the compiler decides to emit a loop
instead of unrolling the 64-element copy), but the conversion of each
element still compiles down to a pair of MOV instructions.
The corresponding unit test has also been updated to avoid transmute, as
it was unnecessary there - the individual array element can be cast with
the `as` operator rather than transmuting the whole array.

Cathedral enthusiant Victor Hugo once said:
“Nothing else in the world ... not all the armies ... is so
powerful as an idea whose time has come.”
He was talking about republicanism vs. monarchy. My friends,
we are on the verge on a change quite possibly bigger than
that: seamless wayland windowing!!
The revolution started by the virtio_wl device is finally making
it's way to virtio_gpu, bringing best-in-class display
virtualization to a wider audience.
The overall approach is described here:
goto.google.com/virtio-gpu-wayland-context
At it's core, virtio-gpu wayland windowing uses the same mechanisms
that another virtio-gpu consumer (say gfxstream or virglrenderer)
uses to submit an opaque command stream to the host. A response
page is allocated by the guest where host commands are place
(gfxstream has been using this mechanism for years).
There are various tables to track the internal context state and
resources. A thread is spun up to poll the Wayland socket. The
asynchronous callback and upcoming virtio-gpu multiple timelines
feature is used to make 3D consumers (gfxstream, virglrenderer)
don't interfere with the Wayland signalling.
In the future, virtio-gpu may be further modifed to perform
multi-queue virtio in-case the single virtio-queue turns out to be
a bottleneck.
As always, look forward to your feedback & questions.
