This reverts commit a999284da2.
This also introduces two extra `use` statements to fix the corresponding
errors in the LUCI build, which did not occur in local builds.
Reason for revert: caused deadlock in virglrenderer
Original change's description:
> rutabaga_gfx: remove fence polling and enable async callback
>
> Now that rutabaga users can provide a callback for fence
> completion, fences no longer need to be polled on the main thread.
>
> Optional polling still occurs for Rutabaga Components that still
> rely on it for other purposes (e.g. virglrenderer for GL query
> checking).
>
> 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.

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on
simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security
boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t
emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as
the virtio standard.
crosvm is currently used to run Linux/Android guests on Chrome OS devices.
