[PATCH ocaml 0/1] RFC: add/switch to dune build system

[Pino Toscano]

ocaml-libvirt is currently built using manually written makefiles, and
an autoconf script to detect libvirt (using pkg-config). While this
seems OK, it has a lot of downsides:
- all the OCaml rules are manually written
- there is some form of duplication in the OCaml rules
- the bytecode vs native build is fragile

Initially named jhbuild, dune is a native OCaml build system which plans
to eventually replace the others (omake, oasis, ocamlbuild), with a
growing user base in the OCaml community.

This is a very simple patch adding support for dune. The idea is to
replace the current autoconf+makefile build system, which can be
removed more or less easily. I'd prefer to not maintain two build
systems at once, so this patch is also a way to start a discussion about
the proposed approach.

Things not yet done (pending the discussion):
- rewrite/simplify the release bits, currently interwonen in the
  makefiles
- update the documentation
- update libvirt-ci
- remove the autoconf+makefile build system
