Prepare 4.0.0 release (#16)

* repacks frontc into three independent packages

The printc command is no longer installed. The `ctoxml` and `calipso`
packages are distributed in separate packages.

* adds tests and more docs

* adds missing files

* adds github actions test

* runs the test only on pull requests

* copies the test artifacts to the test.t folder

to make windows happy, apparently links do not work on windows :)

* adds the missing menhir dependency

* removes deprecated names as they do not woron on macOS and Windows

The difference is in the register of letters, e.g., `Frontc` vs
`FrontC`, but it doesn't really affect the module names so there was
no need to introduce them at all.

+calipso
+=======
+
+The `calipso` package provides a program analysis tool that removes non-structural control-flow from C programs. See https://dblp.org/rec/journals/tsi/CasseFRS02 for more details. The tool provides two binaries, `calipso` and `calipso_stat`
+
+FrontC v3.0 (stable)
+-----------
+
+The [stable][1] branch supports only ANSI C (C89) with partial support for some GNU extensions. This branch is using ocamlyacc as a parser generator and doesn't accept new features, only occasional bug fixes.
+
+
+
+Building and Installing
+-----------------------
+
+The easiest option is to install using [opam][2], e.g.,
+
+```
+opam install FrontC # or calipso, or ctoxml
+```
+
+The command above will install the latest version of the package from the ocaml.org [opam-repositor][3]. To get the current development (not yet released to ocaml.org) version of a package, you can use the `opam pin command`, e.g.,
+
+```
+opam pin FrontC --dev-repo
+```
+
+You can also just clone this repo and do
+```
+make && make install # translates to `dune build && dune install`
+```
+
+If you change anything do not forget to run tests with `make test`.
+
+
+Documentation
+-------------
+
+You can easily get the documentation using odig,
+
+```
+odig doc FrontC
+```
