When processing memory devices (as a reply from QEMU), a bunch of
STREQ()-s is used. Fortunately, the set of strings we process is
the same as virDomainMemoryModel enum. Therefore, we can use
virDomainMemoryModelTypeFromString() and then use integer
comparison (well, switch()). This has an upside: introducing a
new memory model lets us see what places need adjusting
immediately at compile time.
NB, this is in contrast with cmd line generator
(qemuBuildMemoryDeviceProps()), where more specific models are
generated (e.g. "pc-dimm", "virtio-mem-pci", etc.). But QEMU
reports back the parent model, instead of specific child
instance.

When starting QEMU (or when reconnecting to a running one),
qemuMonitorJSONGetMemoryDeviceInfo() is called to refresh info on
memory devices. In here, query-memory-devices is called which
returns info on all memory devices. The result is then iterated
over and for some memory models runtime information is updated.
The rest is to be ignored. Except, when introducing SGX support,
this was turned into an error leaving us unable to start any
domain with virtio-pmem memory device (as virtio-pmem is to be
ignored).

When a QEMU netdev is of type "stream", if the socket it uses for
connectivity to the host network gets closed, then QEMU will send a
NETDEV_STREAM_DISCONNECTED event. We know that any stream netdev we've
created is backed by a passt process, and if the socket was closed,
that means the passt process has disappeared.
When we receive this event, we can respond by starting a new passt
process with the same options (including socket path) we originally
used. If we have previously created the stream netdev device with a
"reconnect" option, then QEMU will automatically reconnect to this new
passt process. (If we hadn't used "reconnect", then QEMU will never
try to reconnect to the new passt process, so there's no point in
starting it.)
Note that NETDEV_STREAM_DISCONNECTED is an event sent for the netdev
(ie "host side") of the network device, and so it sends the
"netdev-id" to specify which device was disconnected. But libvirt's
virDomainNetDef (the object used to keep track of network devices) is
the internal representation of both the host-side "netdev", and the
guest side device, and virDomainNetDef doesn't directly keep track of
the netdev-id, only of the device's "alias" (which is the "id"
parameter of the *guest* side of the device). Fortunately, by convention
libvirt always names the host-side of devices as "host" + alias, so in
order to search for the affected NetDef, all we need to do is trim the
1st 4 characters from the netdev-id and look for the NetDef having
that resulting trimmed string as its alias. (Contrast this to
NIC_RX_FILTER_CHANGED, which is an event received for the guest side
of the device, and so directly contains the device alias.)

QEMU's "reconnect" option of "-netdev stream" tells QEMU to
periodically (period is given in seconds as an argument to the option)
attempt to reconnect to the same passt socket to which it had
originally connected to. This is useful in cases where the passt
process terminates, and libvirtd starts a new passt process in its
place (which doesn't happen yet, but will happen automatically after
an upcoming patch in this series).
Since there is no real hueristic for determining the "best" value of
the reconnect interval, rather than clutter up config with a knob that
nobody knows how to properly twiddle, we just set the reconnect timer
to 5 seconds.
"-netdev stream" first appeared in QEMU 7.2.0, but the reconnect
option won't be available until QEMU 8.0.0, so we need to check QEMU
capabilities just in case someone is using QEMU 7.2.0 (and thus can
support passt backend, but not reconnect)

The 'newapi.xsl' stylesheet was referencing non-existing paths to the
XML files holding ACL permission flags for individual APIs. Additionally
the 'document()' XSL function doesn't even allow concatenation of the
path as it was done via '{$builddir}/src..', but requires either direct
argument or use of the 'concat()' function.
This meant that the 'acls' variable was always empty and thus none of
our API documentation was actually generated with the 'acl' section.
Fix it by passing the path to the XML via an argument to the stylesheet
as the files differ based on which document is being generated.
Since the 'admin' API does not have ACL we need to handle it separately
now in the build system.
