[Qemu-block] [RFC v2 for-2.9 09/10] squash! nbd: Tidy up blockdev-add interface

[Markus Armbruster]

Drop backward -drive server.data.* compatibility gunk.  On squash,
replace commit message's last paragraph "Unfortunately, SocketAddress
is also visible..." by:

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.  You now have to use

    -drive 
if=none,driver=nbd,server.type=inet,server.host=127.0.0.1,server.port=12345
