qemu vhost-scsi devices map to XML roughly like:
<hostdev mode='subsystem' type='scsi_host'>
<source protocol='vhost' wwpn=X/>
</hostdev>
To support vhost-scsi-pci-{non-}traditional in qemu, we
need to to extend the SCSI Host hostdev XML to handle
model= value. This matches the XML model= format used
for mediated devices. This is just the domain_conf bits
and some XML test cases.
Use of virtio-X naming here does not match the hostdev
protocol=vhost nor does it match the qemu vhost-X device
naming, however it's more consistent with all other
model= names in this area, and also matches the
inconsistency of <vsock> devices which use model=virtio
but map to vhost-vsock on the qemu commandline

<disk> devices lack the model= attribute which is used by
most other device types. bus= mostly acts as one, but it
serves other purposes too like determing what target=
prefix to use, and for matching against controller type=
values.
Extending bus= to handle additional virtio transitional
devices will complicate apps lives, and it isn't a clean
mapping anyways. So let's bite the bullet and add a new
<disk model=X/> attribute, and wire up common handling
for virtio and virtio-{non-}transitional

The previous patch made it possible to split multiple commands by
adding newline, but not to split a long single command. The sequence
backslash-newline was being used as if it were a quoted newline
character, rather than completely elided the way the shell does.
Again, add more tests, although this time it seems more like I am
suffering from a leaning-toothpick syndrome with all the \.

I wanted to do a demonstration with virsh batch mode, which
takes multiple commands all packed into a single argument:
$ virsh -c test:///default 'echo a; echo b;'
a
b
but that produced a really long line, so I tried to make it
more legible:
$ virsh -c test:///default '
echo a;
echo b;
'
error: unknown command: '
'
Let's be more like the shell, and treat unquoted newline as a
command separator just as we do for semicolon. In fact, with
that, I can even now mix styles:
$ virsh -c test:///default '
echo a; echo b
echo c
'
a
b

dnsmasq documentation says that the *IPv4* prefix/network
address/broadcast address sent to dhcp clients will be automatically
determined by dnsmasq by looking at the interface it's listening on,
so the original libvirt code did not add a netmask to the dnsmasq
commandline (or later, the dnsmasq conf file).
For *IPv6* however, dnsmasq apparently cannot automatically determine
the prefix (functionally the same as a netmask), and it must be
explicitly provided in the conf file (as a part of the dhcp-range
option). So many years after IPv4 DHCP support had been added, when
IPv6 dhcp support was added the prefix was included at the end of the
dhcp-range setting, but only for IPv6.
A user had reported a bug on a host where one of the interfaces was a
superset of the libvirt network where dhcp is needed (e.g., the host's
ethernet is 10.0.0.20/8, and the libvirt network is 10.10.0.1/24). For
some reason dnsmasq was supplying the netmask for the /8 network to
clients requesting an address on the /24 interface.
This seems like a bug in dnsmasq, but even if/when it gets fixed
there, it looks like there is no harm in just always adding the
netmask to all IPv4 dhcp-range options similar to how prefix is added
to all IPv6 dhcp-range options.

qemuProcessQMPStart starts a QEMU process and monitor connection that
can be used by multiple functions possibly for multiple QMP commands.
The QMP exchange to exit capabilities negotiation mode and enter command
mode can only be performed once after the monitor connection is
established.
Move responsibility for entering QMP command mode into the
qemuProcessQMP code so multiple functions can issue QMP commands in
arbitrary orders.
This also simplifies the functions using the connection provided by
qemuProcessQMPStart to issue QMP commands.
Test code now needs to call qemuMonitorSetCapabilities to send the
message to switch to command mode because the test code does not use the
qemuProcessQMP command that internally calls qemuMonitorSetCapabilities.
