While the current design works well for progressive content, in
interlaced content a common strategy is to decode both fields to the
same Surface.
Thus, add support for sharing the underlying Surface. This means that we
can only retrieve the Surface if we are the last Picture with a
reference to it.
While we are at it: only retrieve Surfaces if we are the last users
In preparation for interlaced decoding support, only retrieve Surfaces
back into the surface pool if we are the last users. This means that the
surface will not be dropped until both of its fields have been dropped.

The current crosvm implementation is using
`GuestMemory::checked_offset()` for the following two cases:
(1) To get a valid `GuestAddress` representing `addr + offset`.
(2) Guarantee that the memory range `[addr, addr+offset]` is valid.
However, using `checked_offset()` for the case (2) is wrong because the
method only checks if the end address `addr+offset` is valid and doesn't
check if an invalid region exists between `addr` and `addr+offset`.
So, this CL adds `GuestMemory::is_valid_range()` to replace the (2)
cases.

Current implementation of vhost-user backend devices cannot directly
send vhost-user messages from the backend to the frontend since the
established connection is stored directly to `VhostShmemMapper`. This
limits the messages that could be sent to memory share-related messages.
To overcome this limitation, introduce struct `VhostBackendReqConnection`
which exposes the required backend to frontend requests and keeps track of
the underlying transport (struct `Slave`), and refactor `Slave` out from
current VhostShmemMapper.The state of the connection is managed using enum
`VhostBackendReqConnectionState`.
This patch also moves the timing of when `BackendReqHandler` is created in
the frontend to when `VhostUserProtocolFeatures::SLAVE_REQ` is negotiated
when creating VhostUserHandler.

pread only works for seekable files, so, for example, a pipe could not

There is a possibility of breaking something with this change. Suppose
crosvm was passed an input FD with the cursor at the end of a non-empty
file. Before the async console would read the full file from the
beginning, but now it would immediately EOF.
Another difference is that if the device is reset and then reactivated,
it will continue reading from where it left off instead of restarting at
the beginning of the input.
In both cases, I think the new behavior is better and additionally
matches the non-async console's behavior. The async console is
relatively new, so hopefully no one is depending on this part of its

Per virtio-video spec, if the device encounters a field with value it
does not support, it should update the field with a valid value and then
return that.
It's actually debatable whether an empty plane array is allowed in the
first place, but this seems to be what happens in the case we use a non-
default format (everything but NV12) from FFmpeg v4l2m2m. Moreover, the
guest kernel currently ignores SetParams errors, so it seems justifiable
that we should avoid rejecting this input and instead gracefully handle
it.
With this change + later commit introducing the FFmpeg encoder, FFmpeg
in the guest works with `-pix_fmt yuv420p -c:v vp8/h265_v4l2m2m`. Note
that for VP8 a WebM container should be used. VP9 was not supported as

We were already accepting AvFrame for swscale inputs, but for the output
a different SwConverterTarget trait was being used.
The old interface had a few issues:
- The use of memory mapping traits, putting a dependency on crosvm/base
- Insufficient metadata, not being able to represent custom padding on
the stride or non-contiguous plane layouts
- Inconsistency between input and output types
In this patch, we:
1. Introduce a AvFrame-based API to replace the old SwConverter API.
2. Add a TryAsAvFrameExt extension trait inside devices/ to convert
virtio handles to AvFrames.
(This is placed inside devices to avoid ffmpeg depending on base.)
3. Add a new wrapper type, MemoryMappingAvBufferSource, that wraps a
MemoryMappingArena and implements AvBufferSource for it. This was
technically not sound, but it's a low-risk attack vector that we
implicitly allowed before. The patch doesn't change the behavior; it
just makes this assumption more explicit.

In case of GuestPages the stride is obtained from the SetParams request
which is specified as 0 for output buffers in the virtio-video protocol.
This obviously doesn't work, and replacing the use of stride with the
plane size fixes it.

This adds:
- A buffer size field for each plane
- Width, height, format field for each image
This is for introducing helpers to convert video GuestResources into
AvFrames.
In practice, these metadata were readily available either from the
protocol or through rubataga RPCs, but they have not been stored in the
GuestResource struct. With these change these fields would be available
for usage in constructing AvFrames.
A tricky topic is the source of the metadata. Right now, neither the
virtio_video_params struct nor virtio-gpu backend metadata alone can
provide all the metadata we need. See code comment in
GuestResource::from_virtio_object_entry and go/crosvm-enc-ffmpeg for
future work discussions.

V4L2 clients such as FFmpeg goes through a configuration sequence like
the following:
1. Set input format
2. Register input buffers
3. Set output format
4. Register output buffers
Right now, this fails at 3. because the format change is rejected due to
existing registered input buffers. However, none of the encoder
functions are called yet at this point, and a configuration sequence
like above is supposed to work.
Relax the check to allow for compatibility. As noted in code this is an
over-relaxation that might cause unintended behavior if a format change
happens after a ResourceQueue request (which calls encode()), but I'm
not aware of any implementation actually doing that, so this will be a
TODO for the future.

The feature is automatically enabled for the chromeos feature,

Adds a script that copies the bindings we need upstream. We cannot
use the original repository, as it's part of the large platform2 git
repository, and the original build.rs depends on ChromeOS tooling to
generate these bindings.
So instead, this change adds a script that can be called from a
chromiumos checkout of crosvm to update the upstream bindings.
This allows us to enable certain features that talk to ChromeOS
dbus services. They won't be functional upstream, but at least we
can compile and test the code.
To make things more consistent, we no longer replace the crate
with the ChromeOS version when building for ChromeOS.

It used to use File instead. In VirtioGpu::export_fence() and
VirtioGpu::export_resource(), we had to turn SafeDescriptor into
File, which is not supported on Windows (to avoid converting a
SafeDescriptor that is not a file handle to a File). To make them
more platform-agnostic, we replace them with SafeDescriptor.

The generic type used in read_config() and write_config() was only used
to check the offset against the size of that type; the backend device is
capable of checking this itself, so we can drop the type from the
function signatures.
Additionally, fix the config functions to use the offset rather than
reading/writing the whole config and copying out the relevant parts.
This makes the config function implementation identical for all
vhost/user/vmm/ code.
