Cloud Hypervisor allows either the serial or virtio console to output to
TTY, but TTY input is pushed to both.
This is not correct. When Linux guest is configured to spawn TTYs on
both ttyS0 and hvc0, the user effectively issues the same commands twice
in different TTYs.
Fix this by only direct input to the one choice that is using host side
TTY.

The command which is mentioned in the README is wrong. We have two
cofigs one for x86_64 and another for aarh64. Previously it was a single
config. After adding the configs the read me was not modified. This
patch fixes the issue.

In order to follow the virtio-fs development, we rely on the latest
development branch regarding the virtio-fs daemon. It will be now build
from virtio-fs-dev branch from the virtio-fs maintainers repository.

Move to latest vhost version, as it contains the updated list of
vhost-user protocol features along with the updated list of virtio-fs
slave commands.
This will allow Cloud-Hypervisor to work with latest virtiofsd binary.

EpollHelper allows the removal of much duplicated loop handling code and
instead the device specific even handling is delegated via an
implementation of EpollHelperHandler.

This is required for implementing virtio-net as the epoll RawFd must be

Port virtio-block device to the new EpollHelper. This required moving
the queue EventFd ownership to BlockEpollHandler.
Signed-off-by: Rob Bradford <robert.bradford@intel.com>
This is a helper for implementing the worker thread for virtio devices
and in particular handles special behaviour for pause and kill events.
The device specific event handling (for the queues themselves) is
delegated to a method invoked on a new EpollHelperHandler trait. This
method is passed the event as well as the EpollHelper so that it can
operate on the handler in order to manage events itself (required for
virtio-net.)

This commit enables some mmio-related integration test cases on
AArch64, including:
* some vhost_user test cases
* virtio-blk test cases
* pmem test cases
Also this commit contains a bug fix in creating virtio-blk device.
Previously, when creating the FDT, the virtio-blk device was
labeled in the reverse order of address allocation.

Make set_gsi_routing take a list of IrqRoutingEntry. The construction of
hypervisor specific structure is left to set_gsi_routing.
Now set_gsi_routes, which is part of the interrupt module, is only
responsible for constructing a list of routing entries.
This further splits hypervisor specific code from hypervisor agnostic
code.
