Xen's xl config format has long supported specifying multiple IP
addresses for virtual interfaces. E.g.
vif = [ "ip=10.0.0.1 10.1.1.1 2000::1, ..." ]
Add support for converting multiple IP addresses to/from domXML.

Migration never removes any configuration files on the destination host.
Thus when the domain is already defined on the destination, it will stay
persistent even after migration without --persist.

When reconnecting to a running domain started by old libvirt, which did
not change host-model into a custom CPU definition, we replace the CPU
definition with a specific CPU model from host capabilities. However,
that CPU model may not be supported by the running qemu process. We need
to translate the CPU model to one of the models which libvirt could have
used when starting the domain.

Since we are re-detecting the backing chain after pivoting to the active
block commit target (or block copy target) the disk index needs to be
reset to 0. This is necessary since we move a member of the backing
chain to disk->src but clear indexes only starting from
disk->src->backingStore. The freshly detected images have indexes
starting from 1, but since we've pivoted into an image which was
previously a backing store it would have a non-0 index.
The lookup function would then return the top of the chain for queries
like 'vda[1]' instead of the first backing store.
This problem will not be present once we keep the disk indexes stable.

Currently we only describe setting the CN field for server certs. This leads
to inevitable pain for users who set it to the fully qualified hostname and
then use a unqualified hostname or IP address to connect in the URI. Describe
the usage of Subject Alt Name extensions, to provide multiple hostnames and
IP addresses. This will help users avoid the classic mistake and is important
future proofing, since at least in browsers, TLS libraries no longer use the
CN field for validation, mandating use of SAN info instead.

The unprivileged libvirtd does not support nwfilter config, by leaves the
driver active. It is supposed to result in all APIs being an effective
no-op, but several APIs rely on driver->nwfilters being non-NULL, or they
will reference a NULL pointer. Rather than adding checks for NULL in many
places, just make sure driver->nwfilters is always initialized.

gettid() is Linux-specific and should not be used in programs
that are intended to be portable.
Unfortunately, it looks like macOS implemented the functionality
and defined SYS_gettid accordingly, only to deprecate syscall()
altogether with 10.12 (Sierra), released last late year.
To avoid compilation errors, call gettid() on Linux only.

Clean up the style a bit w/r/t to not using a unary operator on an
integer value that could be zero - compare vs. zero instead.
Set the def->mem_nodes[*].distances to rdist or ldist inside the
if condition - no need to set outside since the value being set
to is what was fetched.
During cleanup, be sure to initialize the ndistances on error and
use the < 0 comparison not the unary one.
