[libnbd PATCH 0/3] opt_list_meta_context
I'm posting this now, as I'm at the end of a workday and I got things
working for manual experimentation.
Still to do:
- write interop tests for qemu-nbd and nbdkit (including my proposed
patch addition of qemu-nbd -A to show qemu:allocation-depth)
- figure out if we can make 'nbdinfo --map' use the new API to
automatically select all contexts advertised by the server

[libnbd PATCH v2 0/2] opt_list_meta_context
In v2: ack'ed preliminary patches have been pushed, and I've added a
lot of testsuite coverage as well as putting the new API to use in
nbdinfo.
