fa34fae55f ci: Move to personal branch for virtiofsd
The current virtio-fs-dev branch from the official repo is breaking the
build on our Azure VMs because the glibc wrapper for renameat2() syscall
does not exist. This branch fixes the problem while the maintainers are
fixing the issue upstream.

f427d94422 virtio-fs: Update virtiofs daemon parameters
With the latest version of virtiofsd, some changes have been made
to the socket path parameter. This needs to be updated in the cloud
hypervisor codebase, so that our CI keeps running correctly.

Fixes #611

c2ae380503 pci: Refine detection of BAR reprogramming
The current code was always considering 0xffffffff being written to the
register as a sign it was expecting to get the size, hence the BAR
reprogramming detection was stating this case was not a reprogramming
case.

Problem is, if the value 0xffffffff is directed at a 64bits BAR, this
might be the high or low part of a 64bits address which is meant to be
the new address of the BAR, which means we would miss the detection of
the BAR being reprogrammed here.

This commit improves the code using finer granularity checks in order to
detect this corner case correctly.

07bad79fd7 pci: Fix detection of expansion ROM BAR reprogramming
The expansion ROM BAR reprogramming was being triggered for the wrong
reason and was causing the following error to be reported:

ERROR:pci/src/bus.rs:207 -- Failed moving device BAR: failed allocating
new 32 bits MMIO range

Following the PCI specification, here is what is defined:

Device independent configuration software can determine how much address
space the device requires by writing a value of all 1's to the address
portion of the register and then reading the value back.

This means we cannot expect 0xffffffff to be written, as the address
portion corresponds to the bits 31-11. That's why whenever the size of
this special BAR is being asked for, the value being written is
0xfffff800.

38468d3d9b vm-virtio: Improve virtio-console input processing
The way the code is currently implemented, only by writing to STDIN a
user can trigger some input to reach the VM through virtio-console. But
in case, there were not enough virtio descriptors to process what was
retrieved from STDIN, the remaining bits would be transferred only if
STDIN was triggered again. The missing part is that when some
descriptors are made available from the guest, the virtio-console device
should try to send any possible remaining bits.

By triggering the function process_input_queue() whenever the guest
notifies the host that some new descriptors are ready for the receive
queue, this patch allows to fill the implementation void that was left.

e4c3401a33 vm-virtio: Don't waste a descriptor if not filled
In case the virtio descriptor is pulled out of the Queue iterator, it
is important to fill it and tag it as used. This is already done from
the successful code path, but in case there's an error during the
filling, we should make sure to put the descriptor back in the list of
available descriptors. This way, when the error occurs, we don't loose
a descriptor, and it could be used later.

ad223f2b50 fs: Use cache=none by default
The cache= option from the virtiofsd backend is meant to be used
depending on how the user wants to use the guest page cache. For most
use cases, we want to bypass the guest page cache to reduce the guest
memory footprint, which is why "cache=none" should be the default.

"cache=always" is the other option when the user wants to do something
specific by using the guest page cache, but should not be the default
anymore.

e1822cfdad vm-virtio: Implement VIRTIO_IOMMU_F_PROBE feature
By implementing this virtio feature, we let the virtio-iommu driver call
the device backend so that it can probe each device that gets attached.

Through this probing, the device provides a range of reserved memory
related to MSI. This is mandatory for x86 architecture as we want to
avoid the default MSI range assigned by the virtio-iommu driver if no
range is provided at all. The default range is 0x8000000-0x80FFFFF but
it only makes sense for ARM architectures.

vmm: Convert virtio devices to Arc<Mutex<T>>

Migratable devices can be virtio or legacy devices.
In any case, they can potentially be tracked through one of the IO bus
as an Arc<Mutex<dyn BusDevice>>. In order for the DeviceManager to also
keep track of such devices as Migratable trait objects, they must be
shared as mutable atomic references, i.e. Arc<Mutex<T>>. That forces all
Migratable objects to be tracked as Arc<Mutex<dyn Migratable>>.

Virtio devices are typically migratable, and thus for them to be
referenced by the DeviceManager, they now should be built as
Arc<Mutex<VirtioDevice>>.

This allows us to change the memory map that is being used by the
devices via an atomic swap (by replacing the map with another one). The
ArcSwap provides the mechanism for atomically swapping from to another
whilst still giving good read performace. It is inside an Arc so that we
can use a single ArcSwap for all users.

Not covered by this change is replacing the GuestMemoryMmap itself.

This change also removes some vertical whitespace from use blocks in the
files that this commit also changed. Vertical whitespace was being used
inconsistently and broke rustfmt's behaviour of ordering the imports as
it would only do it within the block.
