nbd: Tidy up blockdev-add interface SocketAddress is a simple union, and simple unions are awkward: they have their variant members wrapped in a "data" object on the wire, and require additional indirections in C. I intend to limit its use to existing external interfaces, and convert all internal interfaces to SocketAddressFlat. BlockdevOptionsNbd is an external interface using SocketAddress. We already use SocketAddressFlat elsewhere in blockdev-add. Replace it by SocketAddressFlat while we can (it's new in 2.9) for simplicity and consistency. For example, { "execute": "blockdev-add", "arguments": { "node-name": "foo", "driver": "nbd", "server": { "type": "inet", "data": { "host": "localhost", "port": "12345" } } } } becomes { "execute": "blockdev-add", "arguments": { "node-name": "foo", "driver": "nbd", "server": { "type": "inet", "host": "localhost", "port": "12345" } } } Since the internal interfaces still take SocketAddress, this requires conversion function socket_address_crumple(). It'll go away when I update the interfaces. Unfortunately, SocketAddress is also visible in -drive since 2.8: -drive if=none,driver=nbd,server.type=inet,server.data.host=127.0.0.1,server.data.port=12345 Nobody should be using it, as it's fairly new and has never been documented, so adding still more compatibility gunk to keep it working isn't worth the trouble.

Unfortunately, we cannot just flatten all of the addresses because nbd-server-start still takes a plain SocketAddress. Therefore, we need both and this is most easily achieved by writing the SocketAddress into the code and flattening it where necessary.
