Currently, nmdm console device requires user to specify master and slave
path attributes (such as /dev/nmdm0A and /dev/nmdm0B respectively).
However, making user find a non-occupied device name might be not
convenient, especially for the remote connections.
Update the logic to make these attributes optional. In case if not
specified, use /dev/nmdm$UUID[AB], where $UUID is a domain's UUID.
With this schema it's unlikely nmdm device will clash with other domains
or even other non-bhyve nmdm devices.

Recently virtio-9p support was added to bhyve.
On the host side it looks this way:
bhyve .... -s 25:0,virtio-9p,sharename=/path/to/shared/dir
It could also have ",ro" suffix to make share read-only.
In the Linux guest, this share is mounted with:
mount -t 9p sharename /mnt/sharename
In the guest user will see the same permissions and ownership
information for this directory as on the host. No uid/gid remapping is
supported, so those could resolve to wrong user or group names.
The same applies to the other side: chowning/chmodding in the guest will
set specified ownership and permissions on the host.
In libvirt domain XML it's modeled using the 'filesystem' element:
<filesystem type='mount'>
<source dir='/path/to/shared/dir'/>
<target dir='sharename'/>
</filesystem>
Optional 'readonly' sub-element enables read-only mode.

Support setting a password for the VNC framebuffer using the passwd
attribute on the <graphics/> element, if the driver has the
BHYVE_CAP_VNC_PASSWORD capability.
Note that virsh domxml-from-native does not output the password in the
generated XML, as VIR_DOMAIN_DEF_FORMAT_SECURE is not set when
formatting the domain definition.

Also, add "gop" to the list of model types the <resolution/>

Support modeling of the 'isa' controller for bhyve. User can manually
define any PCI slot for the 'isa' controller, including PCI slot 1,
but other devices are not allowed to use this address.
When domain configuration requires the 'isa' controller to be present,
automatically add it on domain post-parse stage.
Now, as this controller is always available when needed, it's not
necessary to implicitly add it to the bhyve command line, so remove
bhyveBuildLPCArgStr().
Also, make bhyveDomainDefNeedsISAController() static as it's no longer
used outside of bhyve_domain.c.
As more than one ISA controller is not supported by bhyve,
and multiple controllers with the same index are forbidden,
so forbid ISA controllers with non-zero index for bhyve.

bhyve supports intel hda sound devices that could be specified
on the command like using "-1:0,hda,play=$play_dev,rec=$rec_dev",
where "1:0" is a PCI address, and "$play_dev" and "$rec_dev"
point to the playback and recording device on the host respectively.
Currently, schema of the 'sound' element doesn't allow specifying
neither playback nor recording devices, so for now hardcode
/dev/dsp0, which is the first audio device on the host.

Add support for vgaconf driver configuration. In domain xml it looks like
this:
<video>
<driver vgaconf='io|on|off'>
<model .../>
</video>
It was added with bhyve gop video in mind to allow users control how the
video device is exposed to the guest, specifically, how VGA I/O is
handled.
One can refer to the bhyve manual page to get more detailed description
of the possible VGA configuration options:
https://www.freebsd.org/cgi/man.cgi?query=bhyve&manpath=FreeBSD+12-current
The relevant part could be found using the 'vgaconf' keyword.
Also, add some tests for this new feature.

Along with video and VNC support, bhyve has introduced USB tablet
support as an input device. This tablet is exposed to a guest
as a device on an XHCI controller.
At present, tablet is the only supported device on the XHCI controller
in bhyve, so to make things simple, it's allowed to only have a
single XHCI controller with a single tablet device.
In detail, this commit:
- Introduces a new capability bit for XHCI support in bhyve
- Adds an XHCI controller and tabled support with 1:1 mapping
between them
- Adds a couple of unit tests
Like it usually happens, I fixed one thing and broke another:
in 803966c76 address allocation was fixed for SATA disks, but
broke that for virtio disks, because it dropped disk address
assignment completely. It's not needed for SATA disks anymore,
but still needed for the virtio ones.
Bring that back and add a couple of tests to make sure it won't
happen again.
As bhyve for a long time didn't have a notion of the explicit SATA
controller and created a controller for each drive, the bhyve driver
in libvirt acted in a similar way and didn't care about the SATA
controllers and assigned PCI addresses to drives directly, as
the generated command will look like this anyway:
2:0,ahci-hd,somedisk.img
This no longer makes sense because:
1. After commit c07d1c1c4f it's not possible to assign
PCI addresses to disks
2. Bhyve now supports multiple disk drives for a controller,
so it's going away from 1:1 controller:disk mapping, so
the controller object starts to make more sense now
So, this patch does the following:
- Assign PCI address to SATA controllers (previously we didn't do this)
- Assign disk addresses instead of PCI addresses for disks. Now, when
building a bhyve command, we take PCI address not from the disk
itself but from its controller
- Assign addresses at XML parsing time using the
assignAddressesCallback. This is done mainly for being able to
verify address allocation via xml2xml tests
- Adjust existing bhyvexml2{xml,argv} tests to chase the new
address allocation
This patch is largely based on work of Fabian Freyer.
Add virBhyveDriverCreateXMLConf, a simple wrapper around
virDomainXMLOptionNew that makes it easier to pass bhyveConnPtr
as a private data for parser. It will be used later for device
address allocation at parsing time.
Update consumers to use it instead of direct calls to
virDomainXMLOptionNew.
As we now have proper callbacks connected for the tests, update
test files accordingly to include the automatically generated
PCI root controller.
