[PATCH nbdkit UNFINISHED] Add the ability to write plugins in golang.
Sorry Dan, but I really do dislike golang with a passion :-)
Here is a patch that allows you to write nbdkit plugins in golang. As
with C, OCaml and Rust, you can write a plugin in Go which compiles
directly to a .so file that can be loaded into golang, so in that
sense it works completely differently from scripting language plugins
like Perl and Python where there's an

[nbdkit PATCH 0/2] More language bindings for .list_exports
This picks up python and ocaml. Some of our languages are lacking a
number of bindings (for example, lua and perl lack .extents, so I
didn't have anything to copy from), and I felt less comfortable with
golang and rust. But for python and ocaml, I was able to test a
working implementation.

[nbdkit PATCH v3 00/14] exportname filter
It's been several weeks since I posted v2 (I got distracted by
improving libnbd to better test things, which in turn surfaced some
major memory leak problems in nbdsh that are now fixed). Many of the
patches are minor rebases from v2, with the biggest changes being
fallout from:
- patch 2: rename nbdkit_add_default_export to nbdkit_use_default_export
- overall: this missed 1.22, so update
