The interface to return the event pipe for a backend currently requires
a &File to be returned, which is not very appropriate since the file
only serves as a proxy to the pipe's file descriptor.
Although libvda uses this structure to return its event pipe, this won't
be the case for all backends, so change the interface to return a
non-owned Descriptor, which is more generic and suitable to the task.

Cuttlefish's streaming server, which acts as a Wayland compositor
in order to receive display framebuffers from Crosvm, needs some
mechanism to tell which Wayland surface corresponds to which display
(a "display" is a "scanout" in virtio-gpu terminology).
Wayland object ids can not be directly used for this as all Wayland
objects share a single global id space (so the first created Wayland
wl_surface surface object may have id = 15).
Previously, the case of unchanging displays was handled by enforcing
the creation order of surfaces within Crosvm so that Cuttlefish's
streaming server (which is a Wayland compositor) could assume the
creation order corresponded to the display order. However, this still
experienced issues (b:186580833) when surfaces were destroyed and
later recreated when handling `set_scanout(..., resource_id = 0)`
commands.
There is also an ongoing effort to support adding and removing
displays at runtime in (see aosp/1671968) which experiences the
same issue. When surfaces are arbitrarily created and destroyed,
Cuttlefish's streaming server has no way to determine which Wayland
surface corresponds to which display.
To solve all of this, this change introduces an extension to allow
Wayland clients (Crosvm) to attach additional metadata (scanout_id)
to Wayland objects (surfaces) so that Wayland compositors (Cuttlefish's
streaming server) can exactly determine which surfaces correspond
to which displays. I will attempt to upstream this protocol (tracked
in b:191901112).

Added preliminary version of keyboard and pointing device routine
for wayland implementation. The pointing input is wired as a multi
touch device. Due to the fact that wayland client is callback based,
all the necessary incoming events are serialized and stashed in the
temp circular buffer and then processed afterwards from the main event
loop.
Known issues:
1. Mouse input can't be properly wired inside the guest as a mouse
device without pointer locking, but this is not what we want. The
approach emulates it as a multitouch device, but, of course, it
implies limitations in functionality. Limitations include cursor
in the VM that doesn't move in unison with the host cursor.
2. I kept the mouse cursor surface since it's not decided yet which
approach for handling pointing input device will be used (see #1).
Removing the mouse surface in the guest would remove the lagging
guest cursor. The alternatives to the multi-touch device are:
"- Relative mice (e.g. a typical PC mouse). These are relative
devices, meaning they send deltas from the current cursor
position. Some apps like games rely on these events.
- Touchscreens (multitouch, single touch). These are absolute
devices, and are much easier to implement seamless guest/host
input for.
- Touchpads (these are absolute devices). I'm not sure these are
really compelling for any use case." -nkgold@
3. This code is for POC purpose only, so there are still lot of minor
issues and negligence in it.
Looking forward for your comments and proposals.

Add a constructor for building a VDA-backed encoder instead of requiring
the user to build one.

The current generic Worker code is being instanciated once per kind of
video decoder and encoder. This results in quite a bit of duplication to
avoid one virtual call per device event, and also prevents us from
selecting the codec backend dynamically.
Convert that code to use a Device trait object instead for both
simplicity and flexibility.

Move the backend code into a module of the same name, to mirror the
structure used by the decoder.

Move VDA code that is used by both the decoder and encoder into its own
module, so it can be easily included (or not) during compilation.
