This CL expands the existing boot.rs test to not just boot a kernel
but also provide a debian-based rootfs and a special init binary
that is used to communicate between test code and the guest VM.
The delegate binary listens for commands on /dev/ttyS1 and returns
the stdout of the executed command.
This allows the test code to setup pipes for the serial device to
issue commands in the client and receive the command output, which
provides a good foundation for tests of basic functionality without
the need to pass test binary code into the guest.
The integration tests will pull a prebuilt kernel and rootfs image
from cloud storage unless local files are specified via ENV variables.
The integration_tests/guest_under_test directory contains the files
needed to build and upload those prebuilts.

This CL adds the foundation for running tests consistently
in Kokoro and locally, for both x86 and aarch64.
The crosvm_builder is similar to the original image from
docker/crosvm.Dockerfile.
The main difference is that ChromeOS dependencies are not
compiled into the container, but built at runtime.
The crosvm_aarch64_builder installs the build enviornment
to cross-compile crosvm for aarch64. The tests are run
with user-space emulation using qemu-aarch64-static.
See ci/README.md for instructions on how to use these
builders.
Tests on aarch64 cannot all be run using user-space
emulation. We will need a VM to pass all smoke tests,

Instead of the balloon balancing available memory between the host and
guest, available memory above the critical margin is balanced. Where
critical margin is the level that the host/guest starts reclaiming
memory or killing processes. See comments above impl BalloonPolicy for
explanation.
In addition, balloon size dependent bias is introduced to encourage
large balloons to deflate, and small balloons to inflate. This bias is
needed for multivm.LifecycleShifting.arc_host to pass, as sometimes
without the bias the balloon is inflated so much that the first App in

to directly access file pages.
Specifically, FUSE_SETUP_MAPPING and FUSE_REMOVE_MAPPING operations are
supported.
This option can be used by specifing `dax` option when mount a file system in
the guest.
The DAX optoin improved file I/O performance in most cases.
In Fio tests, both of read and write score were improved by 1.3-14x depending on
test cases.
In Blogbench tests, which create many small files, DAX improved the write score
by 1.5x while the read score was reduced to ~25% (20391 -> 4593).

As part of moving from RawFd to RawDescriptor and related types
(https://crrev.com/c/2462330), the USB attach code was modified to
accept a MaybeOwnedDescriptor instead of a MaybeOwnedFd. Since
MaybeOwnedDescriptor::Owned contains a SafeDescriptor instead of a File,
and the usb_util Device::new() constructor requires a File, a conversion
is required. However, the patch mentioned above used as_raw_descriptor
and File::from_raw_descriptor to do this conversion, but this leaves
both the SafeDescriptor and the newly-created File assuming ownership of
the USB fd. When the SafeDescriptor went out of scope, the fd would be
closed, causing the fd in the File to be invalid (meaning the USB device
does not function at all).
This would show up in the crosvm logs like this:
[devices/src/usb/host_backend/utils.rs:61] fail to submit transfer IoctlFailed(2151175434, Error(25))
[devices/src/usb/xhci/xhci_transfer.rs:399] backend is already disconnected
To fix this, use into_raw_descriptor rather than as_raw_descriptor to
transfer ownership out of the SafeDescriptor without closing the fd.

Pointers in rust don't implement Send or Sync and so any struct that
contains a raw pointer doesn't implement those traits either. However,
there's nothing inherently unsafe about sending a pointer across thread
boundaries. The only unsafety comes from actually de-referencing the
pointer, which already requires an unsafe block.
Explicitly implement Send + Sync for IoSliceMut since the iovec
internally holds a *mut c_void, which prevents those traits from being
auto-implemented. Send + Sync is also implemented by
std::io::IoSliceMut, which is almost exactly the same as our IoSliceMut,
so that can provide some additional reassurance that this is safe.
Also add a missing copyright header in the file.

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.

This CL
- simplifies ac97_bus_master audio thread spawn logic
- makes data ownership more clear for future maintenance
- saves several redundant lock calls
High level design:
ac97_bus_master <=> one AudioThreadInfo for each Ac97Function
<=> start / stop an AudioWorker
Changes in this CL:
- Add AudioWorker which contains the data, logic inside spawn::thread()
and some controls which own by AudioThreadInfo
- Remove `fn audio_thread`.
- Make AudioThreadInfo an audio thread control interface for each
Ac97Function
- `start` consumes an worker and spawn a running thread
- `stop` stops the thread and destroy the worker
- Add is_running support
- Combine several regs.lock() calls to save mutex lock time.
- Add create_audio_worker to create AudioWorker

These don't work without a kernel change that we never merged. Arcvm
doesn't need these anymore so just drop them.
