[Libguestfs] [RFC nbdkit PATCH 0/4] Progress towards .list_exports

[Eric Blake]

This takes Rich's API proposal and starts fleshing it out with enough
meat that I was able to test 'nbdkit eval' advertising multiple
exports with descriptions paired with 'qemu-nbd --list'.

Eric Blake (3):
  server: Add exports list functions
  server: Prepare to use export list from plugin
  sh, eval: Add .list_exports support

Richard W.M. Jones (1):
  server: Implement list_exports.
