[PATCH libnbd v2 0/6] Test connection states.
Patch 1/6 was posted before and I didn't change it:
https://www.redhat.com/archives/libguestfs/2019-May/thread.html#00134
That doesn't necessarily mean I shouldn't change it, I'm posting
it again because the other patches depend on it.
The main change in this series is we add three new API functions:
nbd_aio_is_created - connection has just been created

[PATCH libnbd] api: Get rid of nbd_connection.
This isn't quite finished because not all of the tests or examples
have been updated, but it demonstrates an idea: Should we forget about
the concept of having multiple connections managed under a single
handle?
In this patch there is a single ‘struct nbd_handle *’ which manages a
single state machine and connection (and therefore no nbd_connection).
To connect to a multi-conn server you must
