We will need to have console output from the guest only for debugging
purposes. As a result, we can turn-off both the serial and
virtio-console devices by default for better boot time.

Variables in rust will be dropped at the end of the function.
In function real_main the trace will be shut down by `tracer::end_tracing()`,
but at this time the root span is in an active state, so this root span
will not be sent to the trace collector.
This can be fixed by dropping the root span manually.

The variable for 'name' in config-settings.go.in was previously
hardcoded as "kata". In e7c42fb it was changed to the runtime name,
which is "kata-runtime". Add a variable to specify a syslog identifier
for consistency for tests and documentation that use it.

wait_for_pci_device() waits for the PCI device at the given path to become

pci::Slot represents a PCI slot. However, in all cases where we use it, we
actually care about addressing a specific PCI function. So, at the moment
we can only refer to function 0 in each slot.
Replace pci::Slot with pci::SlotFn to represent both the slot and function.

The guest kernel configuration suggested for Kata, and which is used by the
CI didn't include CONFIG_PCI_MMCONFIG. That's kind of weird, MMCONFIG is
the modern normal way of handling configuration cycles.
In addition, due to a complex set of interactions through the ACPI code,
disabling MMCONFIG means that SHPC hotplug doesn't work: the driver is
included in the guest kernel, but will fail to probe on PCI to PCI bridges,
meaning it won't actually be activated.
Enable MMCONFIG so that we suggest and testa more typical guest kernel
configuration.

From the endpoints string described through the configuration file, we
build a hash set of allowed enpoints. If a configuration files does not
include an endpoints section, we assume all endpoints are not allowed.
If there is no configuration file, then all endpoints are allowed.
Then for every ttrpc request, we check if the name of the endpoint is
part of the hashset. If it is not, then we return ttrcp::UNIMPLEMENTED.

When the kernel command line includes a agent.config_file=<path> entry,
then we will try to override the default confiuguration values with the
ones we parse from a TOML file at <path>.
As the configuration file overrides the default values, we need to go
through a simplified builder that convert a set of Option<> fields into
the actual AgentConfig structure.

Not all routes have either a gateway or a destination IP.
Interface routes, where the source, destination and gateway are undefined,
will default to IP v4 with the current is_ipv6() check even when they
are v6 routes.
We use the provided gRPC Route.Family field instead. This field is built
from the host netlink messages, and is a reliable way of finding out
a route's IP family.
Fixes: #2768

Our check for the IP family is working as long as we have either a
gateway or a destination IP. Some routes are missing both.
The RT netlink messages provide the IP family information for each
route, so we can carry that piece of information up to the guest. That
will allow for a more reliable route IP family determination.

We need to be able to get the IP family from the netlink route meesages,
and the Route.Family field only got recently added to the netlink
package.
The update generates static check warnings about the call for
nethandler.Delete() being deprecated in favor of a Close() call instead.
So we include the s/Delete()/Close()/ change as part of this PR.

Reduce the cloud-hypervisor log level from `Debug` to `Info` when hypervisor
debug is enabled. This is required since `Debug` level:
- Is overkill for debugging hypervisor failures.
- Effectively hides the output from the guest kernel and userland: CLH
generates so much output that the output from the guest gets "lost in
the noise" (experiments show that for each full CLH debug message, at most
1 _byte_ of guest output is displayed).
