It's possible to compile the gpu device without virgl_renderer.
In fact, in many instances, this may be required.
This builds the gpu device default, but only with --gpu do I see
/dev/dri/renderN128, so this should be safe.

rutabaga_gfx is a cross platform, Rust-based, Wayland and
Vulkan-centric Virtual Graphics Interface (VGI).
Apologies for the mega-change, but it was hard to do this piece
by piece.
The rationale for this change is:
1) Android graphics virtualization experts have been proposing
for a VGI for many months (years?). Their goal is to boot
Android anywhere, everywhere.
2) For the {wayland, cross-domain} context type prototype,
it's desirable to create a {wayland, camera} connection at the
appropriate time. Details can be found in the code, though the
RutabagaChannels have yet to be hooked up.
There's a high chance neither effort will work. As such,
rutabaga is just a prototype.
However, even (1) and (2) don't end up working, this
refactor/cleanup by itself makes a ton of sense.
Here's a summary of revelant changes:
* Removed auto-generated {p_defines, p_format, virgl_protocol}.
These files were added for tests when bringing up crosvm-gpu,
and AFAICT these tests are not run. There's actually now a
commit queue for virglrenderer changes and container boot tests
that provides excellent coverage.
* Removed command_buffer.rs. Used only for the previously
mentioned tests. It's quite nice, but couldn't determine the right
place to put it. Maybe data_model? But removed it in the interim.
* Removed {write_from_guest_memory, read_to_volatile}. The same
basic functionality has been moved into {transfer_write,
transfer_read} in Rutabaga.
* Removed VirtioResource, Virtio3DResource, Virtio2DResource,
and VirtioGfxStreamResource in favor of VirtioGpuResource and
RutabagaResource. This leads to less duplication and clearer
separation between external library functions and VMM functions.
* Moved display and hypervisor memory management functions to
virtio_gpu.rs. This is because external components do not interface
with this functionality, and there was a lot of duplication (for example
map/unmap blob).
* Added context management between gfxstream and virglrenderer.
* Added separate gfxstream and virglrenderer flags.
* Clearer naming.
* Added simple implementations for context init and multiple timelines.
These changes have no effect since all Google kernels don't pass the
revelant flags, but are useful for theoretical {wayland, cross-domain}
prototype.
* Unify RESOURCE_CREATE_3D and RESOURCE_CREATE_2D handling.
* Better error handling.

Calls to the kvm crate have been replaced by calls to hypervisor and
devices::irqchip. Plugin is unchanged and still KVM-specific.
x86 creates and configures vcpus on the vcpu thread instead of the main
thread.
Code that still depends on kvm or kvm_sys:
- crosvm_plugin, plugin, and protos use kvm and kvm_sys if built with
the plugin feature
- devices::VfioGroup does a kvm_sys ioctl
- devices::irqchip and hypervisor use kvm_sys. hypervisor uses
kvm::Cap and kvm::CpuId internally for now.

Posix acls are a truly incredible example of API design. The presence
of a default posix acl in a directory completely changes the meaning of
the `mode` parameter for all system call that create inodes. However,
this new behavior only applies when the inode is first created and not
for any subsequent operations that use the mode, like fchmod.
When a directory has a default posix acl, all inodes created in that
directory get the permissions specified in the default acl. The mode
parameter is treated like a umask where any permissions allowed by the
default acl that are not allowed by the mode parameter are blocked. The
actual umask is ignored in this case.
So to handle this properly we need to set FUSE_DONT_MASK to prevent the
kernel driver from preemptively applying the umask. Then we have to
check if the parent directory has a default posix acl and only apply the
umask to the mode if it does not. This also means that we cannot use
`mkdtemp` because that always creates directories with a mode of 0o700
and since the default posix acl calculation only applies on creation and
not on later operations, we need to apply the proper mode in the very
beginning.

Adds a new backend type, gfxstream, that calls out to a C library
implementing the actual rendering.
The purpose is to allow the Cuttlefish and Android Studio Emulator teams
to use crosvm with the current API-forwarding style of rendering
employed in the Android Studio Emulator.
Also, introduces a new key to the --gpu command line interface,
backend=, which selects from different backends. Note that the previous
behavior is now deprecated and will be removed after some time
(when all clients switch over to backend=).
The gfxstream backend itself implements a subset of 3d-related resource
and context creation/transfer/execbuffer commands. Their meaning is
specific to the way in which they are interpreted in the backend
library.
To interface with display, gfx stream backend takes a callback that is
run on guest vsync. The callback is responsible for repainting the
display's contents. gfx stream provides a callback, get_pixels, that can
be used asynchronously. The asyncness is not taken advantage of
currently but will be useful for cases where the client attached to the
VMM might want to update at a different rate than guest vsync.
The guts of the stream backend library is currently defined here:
https://android.googlesource.com/platform/external/qemu/+/refs/heads/emu-master-dev/android-qemu2-glue/emulation/virtio-goldfish-pipe.cpp
The linking of the library is controlled via the feature "gfxstream".
If the feature is turned off, we use a default do-nothing stub impl.
Next steps:
- integrate virtio-gpu-next so as to have host coherent memory for
vulkan
- Figure out low latency command submit/response with SUBMIT_CMD_3DV2

The Ac97 device provides the guest with an audio playback device. All
input devices are stubbed out. Only playback at 48kHz is supported.
The device is emulated by `Ac97Dev` which interfaces with the PCI bus.
`Ac97Dev` uses `Ac97` to drive audio functions and emulate the device
registers. Physical Ac97 devices consist of two parts, the bus master
and a mixer. These two sets of registers are emulated by the
`Ac97BusMaster` and `Ac97Mixer` structures.
`Ac97BusMaster` handles audio samples and uses `Ac97Mixer` to determine
the configuration of the audio backend.

This CL adds a crate `sync` containing a type sync::Mutex which wraps
the standard library Mutex and mirrors the same methods, except that
they panic where the standard library would return a PoisonError. This
API codifies our error handling strategy around poisoned mutexes in
crosvm.
- Crosvm releases are built with panic=abort so poisoning never occurs.
A panic while a mutex is held (or ever) takes down the entire process.
Thus we would like for code not to have to consider the possibility of
poison.
- We could ask developers to always write `.lock().unwrap()` on a
standard library mutex. However, we would like to stigmatize the use
of unwrap. It is confusing to permit unwrap but only on mutex lock
results. During code review it may not always be obvious whether a
particular unwrap is unwrapping a mutex lock result or a different
error that should be handled in a more principled way.
Developers should feel free to use sync::Mutex anywhere in crosvm that
they would otherwise be using std::sync::Mutex.

The virtio PCI spec (4.1.5.2 Notifying The Device) says:
"The driver notifies the device by writing the 16-bit virtqueue index
of this virtqueue to the Queue Notify address."
We were previously registering the notify address specifying
NoDatamatch; switch this to a 16-bit match of the queue index to follow
the specification.

This implements DMABuf allocation type in the virtio wayland
device.
We attempt to locate a supported DRM device prior to engaging
the device jail. If found, the DRM device is passed to the
wayland device code and used to serve DMABuf allocations.
DMABuf support can be disabled by not providing crosvm with
access to any DRM device nodes.
The guest is expected to handle the case when DMABuf allocation
fails and fall-back to standard shared memory.
This initial change uses DRM directly but is structured in a
way that would allow the allocator to be replaced by minigbm
with minimal effort.
