Adds another method for fencing where a rutabaga component may provide
an asynchronous callback for fence completion. When this method is
enabled, fences no longer need to be polled on the main thread.
When async_fence_cb is enabled, optional polling still occurs for
Rutabaga Components that still rely on it for other purposes (e.g.
virglrenderer for GL query checking).
Both the old and new methods of fence handling are supported with this
CL; e.g. timer-based polling and async callback, but timer-based polling
is the only one active. Follow-up CL(s) will switch to using the async
callback for each RutabagaComponent. Support for the old timer-based
polling will be removed after the async callback method stabilizes in
production.
Also, use a BTreeMap rather a HashMap since we only expect a dozen or so
entries at most. In such cases, a BTreeMap is faster.
* v1 (lfrb@collabora.com): remove all polling + add async_cb
* v2 (ryanneph@google.com): re-introduce optional polling to fix
virglrenderer that relies on it for GL query checking.
* v3 (ryanneph@google.com): replace timer-based polling with
eventfd-based poll() signaling for components that want to use it.
* v4 (ryanneph@google.com): add async fence handling beside timer-based
polling to support both for a short time.
This is a pseudo-reland of commit
a999284da2, but modifications have been
made to support both fencing methods simultaneously.

The queue size defines the number of available descriptors, that can be
used for exchanging messages between guest and hypervisor. Each
virtio-video command uses at least 1 descriptor (eg. CMD_QUEUE uses 2).
The amount of descriptors in use depends on the number of sessions and
buffers in input and output video queue.
In the worst case scenario the peak number can reach over 672 for 8
simultaneous streams, with 26 + 16 buffers each just for CMD_QUEUE
commands alone.
If the entire queue is overfilled with CMD_QUEUE for OUTPUT queue only,
the driver has no free descriptors for INPUT queue buffers. This leads
to encoder/decoder starvation, hence no OUTPUT buffer can be produced
and no CMD_QUEUE will finish, which leads to dead locking the device.
This patch increases the queue size with consideration of above details
with some headroom to avoid driver's deadlock.

The top part of gpu_common.policy is supposed to match
common_device.policy, but "prctl" is in this top part and isn't in
common_device.policy. A bit of history:
* prctl used to be in the common_device.policy but was removed in
<https://crrev.com/c/2837307>.
* Even when prctl was in common_device.policy, it had different
arguments than what we allow in gpu_common.policy.
This is a no-op cleanup change.

When multi pcie endpoint devices are connected to one virtual pcie
root port as pcie multi function device, virtual pcie root port couldn't
inject hotplug out interrupt for each removed pcie device. Only one
hotplug out interrupt is needed for all the removed pcie devices.
When the first vfio-pci device send hotplug out vfio command, virtual
pcie root port will inject hotplug out interrrupt. Other vfio-pci device's
hotplug out vfio command just clean virtual pcie root port's structure,
and let virtual pcie root port prepare for the next hotplug in.
