[Libguestfs] [PATCH libnbd v3] Add Go language bindings (golang) (RHBZ#1814538).

[Richard W.M. Jones]

This feature is roughly finished now, although it needs a few more
tests and some examples.

It's pretty much up to par with all the other bindings, but it lacks a
completely safe AIO buffer.  It won't stop you from freeing the buffer
too early) because golang's GC inexplicably lacks a way to declare a
root from C.  I can probably do it with a global variable and ref
counting on the golang side, but ... really?

For ease of review I have placed the generated
golang/src/libguestfs.org/libnbd directory here:
