The semantics around handling ipv4=on|off & ipv6=on|off are quite
subtle to understand in combination with the various hostname addresses
and backend types. Introduce a massive test matrix that launches QEMU
and validates the ability to connect a client on each protocol as
appropriate.

The test requires that the host has ability to bind to both :: and
0.0.0.0, on port 9000. If either protocol is not available, or if
something is already listening on that port the test will skip.

Although it isn't using the QTest APIs, it expects the
QTEST_QEMU_BINARY env variable to be set.

+ * This is the giant matrix of combinations we need to consider.
+ * There are 3 axes we deal with
+ *
+ * Axis 1: Protocol flags:
+ *
+ *  ipv4=unset, ipv6=unset  -> v4 & v6 clients ([1]
+ *  ipv4=unset, ipv6=off    -> v4 clients only
+ *  ipv4=unset, ipv6=on     -> v6 clients only
+ *  ipv4=off, ipv6=unset    -> v6 clients only
+ *  ipv4=off, ipv6=off      -> error - can't disable both [2]
+ *  ipv4=off, ipv6=on       -> v6 clients only
+ *  ipv4=on, ipv6=unset     -> v4 clients only
+ *  ipv4=on, ipv6=off       -> v4 clients only
+ *  ipv4=on, ipv6=on        -> v4 & v6 clients [3]
+ *
+ * Depending on the listening address, some of those combinations
+ * may result in errors. eg ipv4=off,ipv6=on combined with 0.0.0.0
+ * is nonsensical.
+ *
+ * [1] Some backends only support a single socket listener, so
+ *     will actually only allow v4 clients
+ * [2] QEMU should fail to startup in this case
+ * [3] If hostname is "" or "::", then we get a single listener
+ *     on IPv6 and thus can also accept v4 clients. For all other
+ *     hostnames, have same problem as [1].
+ *
+ * Axis 2: Listening address:
+ *
+ *  ""        - resolves to 0.0.0.0 and ::, in that order
+ *  "0.0.0.0" - v4 clients only
+ *  "::"      - Mostly v6 clients only. Some scenarios should
+ *              permit v4 clients too.
+ *
+ * Axis 3: Backend type:
+ *
+ *  Migration - restricted to a single listener. Also relies
+ *              on buggy inet_parse() which can't accept
+ *              =off/=on parameters to ipv4/ipv6 flags
+ *  Chardevs  - restricted to a single listener.
+ *  VNC       - supports multiple listeners. Also supports
+ *              socket ranges, so has extra set of tests
+ *              in the matrix
