099cdd2af8 virtio-devices, vmm: vdpa: Implement live migration support
Vdpa now implements the Migratable trait, which allows the device to be
added to the DeviceTree and therefore allows live migrating any vDPA
device that supports being suspended.

Given a vDPA device can't be resumed from a suspended state without
having to reset everything, we don't support pause/resume for a vDPA
device, as well as snapshot/restore (which requires resume to be
supported).

In order for the migration to work locally, reusing the same device on
the same host machine, the vhost-vdpa handler is dropped after the
snapshot has been performed, which allows the destination VM to open the
device without any conflict about the device being busy.

2b150ac2ea pci, virtio-devices: Restore proper BAR type
When restoring a VM, the BAR type can be found directly from the
snapshot resources. It is more reliable than the previous method which
was using self.use_64bit_bar from VirtioPciDevice because at the time
the BARs are allocated, the VirtioDevice hasn't been restored yet,
meaning the way to determine the value of use_64bit_bar is wrong for a
device like vDPA. At this time, the device type is not known and relying
on the stored resources is the only reliable way.

76dbf85b79 net: Give the user the ability to set MTU
Add a new "mtu" parameter to the NetConfig structure and therefore to
the --net option. This allows Cloud Hypervisor's users to define the
Maximum Transmission Unit (MTU) they want to use for the network
interface that they create.

In details, there are two main aspects. On the one hand, the TAP
interface is created with the proper MTU if it is provided. And on the
other hand the guest is made aware of the MTU through the VIRTIO
configuration. That means the MTU is properly set on both the TAP on the
host and the network interface in the guest.

f38056fc9e virtio-devices, vmm: Simplify virtio-mem resize operation
There's no need to delegate the resize operation to the virtio-mem
thread. This can come directly from the vmm thread which will use the
Mem object to update the VIRTIO configuration and trigger the interrupt
for the guest to be notified.

In order to achieve what's described above, the VirtioMemZone structure
now has a handle onto the Mem object directly. This avoids the need for
intermediate Resize and ResizeSender structures.

a9924df2b8 virtio-devices: Custom EpollHelper::run/VirtioCommon:reset for fuzz
It provides fuzzer a reliable way to wait for a sequence of events
to complete for virtio-devices while not using a fixed timeout to
maintain the full speed of fuzzing.

Take virtio-block as an example, the 'queue event' with a valid
available queue setup can trigger a 'completion event'. This is a
meaningful virtio-block code path of processing guest inputs which is
our target for fuzzing virtio devices.

a391bce781 virtio-devices: console: Detect PTY connection/disconnection
Through multiple changes, this patch aims at providing a reliable
solution for detecting the state of the PTY's connection. Being able to
find out when the other end of the PTY is connected is essential to
prevent the loss of data being output through the PTY. When the PTY
isn't connected, the output is buffered through the SerialBuffer, the
same solution that was created for the serial port initially.

Fixes #4521

9d2e835d14 virtio-devices: Extend EpollHelper and EpollHelperHandler
Extending and improving both the structure and the trait allows for more
flexibility regarding what can be achieved with the epoll loop. It
allows for a timeout to be configured instead of the default blocking
behavior. There is a new method in the trait to notify the caller that
the timeout has been reached. And there's a new knob to be notified with
the full list of events before the internal code will actually loop over
every event.

All of these new features are not affecting the previous behavior, and
using EpollHelper::run() should be unchanged.
