The same way we mask the writes coming from the guest to the message
control register related to MSI-X capability, let's do the same for MSI.
The point is to prevent the guest from writing to read-only bits.
The correct writable bits for MSI are only bits 0, 4, 5 and 6 of 2nd
16-bit word.
Those are:
* MSI Enable: 0
* Multiple Message Enable: 6-4
See "Table 7-39 Message Control Register for MSI" from
"NCB-PCI_Express_Base_5.0r1.0-2019-05-22.pdf".

Starting from Rust 1.56 Cargo supports specifying the minimum supported
rust version (MSRV) via "rust-version". If the compiler version is not
satisfied, Cargo prints an error and exits early.
MSRV is useful information to packagers. Using this field also saves us
from adding another file to the tree.
The version is currently set to 1.54, which is tested to build Cloud
Hypervisor successfully. Although anyone who uses 1.54 will see a
warning because "rust-version" is only introduced in 1.56. The warning
can be safely ignored.

This commit adds `translate_gva` for x86/KVM. The same name function is
already implemented for MSHV, but the implementation differs as
KVM_TRANSLATE does not take the flag argument and does not return status
code. This change requires the newer version of kvm-ioctls [1].

`translate_gva` returns mshv-specific type `hv_translate_gva_result`.
This return type is not a problem since this function is implemented
only for mshv, but we need to remove the type as the same function will
be implemented for KVM in PR #3575. This commit replaces the
mshv-specific type with `u32`.

I incorrectly used the MSI message control register values for the mask
not the the MSI-X control registers.
The correct writable fields for MSI-X are only bits 14 and 15 of 2nd

42b5d4a2f7 has changed how the PciBdf
field of a DeviceNode is represented (from an int32 to its own struct).
To avoid marshelling / demarshelling issues for the projects relying on
the openapi auto generated code, let's propagate the change, updating
the yaml file accordingly.

If `--local` is provided or if the version is not available then build

Dockerfile with a full CI run.

For vhost-user devices, we don't want to loose the vhost-user protocol
feature through the negotiation between guest and device. Since we know
VIRTIO has no knowledge of the vhost-user protocol feature, there is no
way it would ever be acknowledged by the guest. For that reason, we
create each vhost-user device with the set of acked features containing
the vhost-user protocol feature is this one was part of the available
list.
Having the set of acked features containing this bit allows for solving
a bug that was happening through the migration process since the
vhost-user protocol feature wasn't explicitely enabled.
