[Libguestfs] [libnbd PATCH 0/4] Various interop fixes

[Eric Blake]

Some of these affect attempts to connect to older qemu-nbd versions,
some of them were triggered by manual edits to qemu-nbd source code to
provoke various other compliant (if uncommon) server behaviors.

Eric Blake (4):
  starttls: Skip error payload if falling back to unencrypted
  states: Reject payload to NBD_REP_ACK
  meta-context: Skip error payload if server lacks meta_context
  states: Add NBD_OPT_EXPORT_NAME handling
