The Rust manifiest requires a three part version number however we
continue with our plan to use two digits so the last part will not be
used.

test_reboot became flaky after the refactoring of the VM reboot code.
This is because we removed the ability to specify a custom timeout.
This patch fixes the issue by allowing a custom timeout of 120s to be
set.

Because the http thread no longer needs to create the api socket,
remove the socket, bind and listen syscalls from the seccomp filter.

Instead of using the http server's method to have it create the
fd (causing the http thread to need to support the socket, bind and
listen syscalls). Create the socket fd in the vmm thread and use the
http server's new method supporting passing in this fd for the api
socket.

This allows the guest to reprogram the offload settings and mitigates
issues where the Linux kernel tries to reprogram the queues even when
the feature is not advertised.
Fixes: #2528

Rather than erroring out and stalling the queue instead report an error
message if the command is invalid and return an error to the guest via
the status field.

Cleanup the control queue handling in preparation for supporting
alternative commands.
Note that this change does not make the MQ handling spec compliant.
According to the specification MQ should only be enabled once the number
of queue pairs the guest would like to use has been specified. The only
improvement towards the specication in this change is correct error
handling if the guest specifies an inappropriate number of queues (out
of range.)

With recent kernels, it is now expected to use "bind" control from the
sysfs in order to bind a specific device to the vfio-pci driver.
The use of "new_id" is still required but it is only needed once per
device type. Let's say you want to bind two virtio-net devices, you will
need to add the device_id:vendor_id pair through "new_id", while you
will be required to use "bind" for each device.

To avoid race issues where the api-socket may not be created by the
time a cloud-hypervisor caller is ready to look for it, enable the
caller to pass the api-socket fd directly.
Avoid breaking current callers by allowing the --api-socket path to be
passed as it is now in addition to through the path argument.

Setting the tap offload should only be done based on the features that
are acked by the guest. Therefore it is incorrect to set these upon
opening the tap.

In the reference vhost_user_net backend don't advertise the offload
features. For correctness we should only advertise them if we can set
them when they are acked by the guest.
