[Qemu-block] [PATCH v4 for-2.9 01/10] rbd: Reject -blockdev server.*.{numeric, to, ipv4, ipv6}

[Markus Armbruster]

We use InetSocketAddress in the QAPI schema.  However, the code
doesn't use inet_connect_saddr(), but formats "host" and "port" into a
configuration string for rados_conf_set().  Thus, members "numeric",
"to", "ipv4" and "ipv6" are silently ignored.  Not nice.  Example:

    -blockdev 
rbd,node-name=nn,pool=p,image=i,server.0.host=h0,server.0.port=12345,server.0.ipv4=off

Factor a suitable InetSocketAddressBase out of InetSocketAddress, and
use that.  "numeric", "to", "ipv4" and "ipv6" are now rejected.
