Embed build informations inside executable

• Project page: https://github.com/ocaml/dune
• Documentation: https://dune.readthedocs.io/

CHANGES:

• Don't select all local implementations in dune utop. Instead, let the
  default implementation selection do its job. (In dune utop, stop selecting all local implementations  dune#2327, fixes dune utop fails with multiple virtual module implementations dune#2323, @TheLortex,
  review by @rgrinberg)

• Check that selected implementations (either by variants or default
  implementations) are indeed implementations. (Check user-written input of implementations dune#2328, @TheLortex, review by
  @rgrinberg)

• Don't reserve the Ppx toplevel module name for ppx rewriters (Generate _ppx.ml rather than ppx.ml dune#2242, @diml)

• Redesign of the library variant feature according to the [RFC] New variant proposal dune#2134 proposal. The
  set of variants is now computed when the virtual library is installed.
  Introducing a new external_variant stanza. (Variants v2 dune#2169, fixes [RFC] New variant proposal dune#2134, @TheLortex,
  review by @diml)

• Add proper line directives when copying .cc and .cxx sources (Unhardcode extensions dune#2275,
  @rgrinberg)

• Fix error message for missing C++ sources. The .cc extension was always
  ignored before. (Unhardcode extensions dune#2275, @rgrinberg)

• Add $ dune init project subcommand to create project boilerplate according
  to a common template. (Add dune init proj subcommand to initialize project skeletons dune#2185, fixes a wizard / quickstart a la oasis would be cool dune#159, @shonfeder)

• Allow to run inline tests in javascript with nodejs (Running inline tests with javascript/nodejs  dune#2266, @hhugo)

• Build ppx.exe as compiling host binary. (Set ppx.exe to be built for the compiling host. dune#2286, fixes Cross-compiling sedlex (ppx) for windows dune#2252, @toots, review
  by @rgrinberg and @diml)

• Add a cinaps extension and stanza for better integration with the
  cinaps tool tool (Add support for cinaps dune#2269,
  @diml)

• Allow to embed build info in executables such as version and list
  and version of statically linked libraries (Formalise the management of versions dune#2224, @diml)

• Set version in META and dune-package files to the one read from
  the vcs when no other version is available (Formalise the management of versions dune#2224, @diml)

• Add a variable %{target} to be used in situations where the context
  requires at most one word, so %{targets} can be confusing; stdout
  redirections and "-o" arguments of various tools are the main use
  case; also, introduce a separate field target that must be used
  instead of targets in those situations. (Add a variable %{target} dune#2341, @aalekseyev)

• Fix dependency graph of wrapped_compat modules. Previously, the dependency on
  the user written entry module was omitted. ([WIP] Unified module handling dune#2305, @rgrinberg)

• Allow to promote executables built with an executable stanza
  (Allow to promote executables to the source tree dune#2379, @diml)

• When instantiating an implementation with a variant, make sure it matches
  virtual library's list of known implementations. (Fix separate installation of implementations dune#2361, fixes separate installation of virtual-modules packages fails dune#2322,
  @TheLortex, review by @rgrinberg)

• Add a variable %{ignoring_promoted_rules} that is true when
  --ingore-promoted-rules is passed on the command line and false
  otherwise (Add ignoring_promoted_rules variable dune#2382, @diml)

• Fix a bug in future_syntax where the characters @ and & were
  not distinguished in the names of binding operators (let@ was the
  same as let&) (fix a typo in ocaml-syntax-shims dune#2376, @aalekseyev, @diml)

• Workspaces with non unique project names are now supported. (Relax restriction on project names being unique dune#2377, fix Internal error when 2 dune-project files have the same name stanza dune#2325,
  @rgrinberg)

• Improve opam generation to include the dune dependncies with the minimum
  constraint set based on the dune language version specified in the
  dune-project file. (2383, @avsm)

• The order of fields in the generated opam file now follows order preferred in
  opam-lib. (@avsm, do opam file generation in the same order as opam lint dune#2380)

• Fix coloring of error messages from the compiler (@diml, Fix coloring of messages from the compiler dune#2384)

• Add warning 66 to default set of warnings starting for dune projects with
  language verison >= 1.11 (@rgrinberg, @diml, fixes Set warnings set according to dune's language dune#2299)

• Add (dialect ...) stanza
  (@nojb, Add support for "dialects" dune#2404)

• Add a --context argument to dune install/uninstall (@diml, Add a --context argument to dune install/uninstall dune#2412)

• Do not warn about merlin files pre 1.9. This warning can only be disabled in
  1.9 (Silence merlin approximation warning in lang < 1.9 dune#2421, fixes merlin approximation warning is not always actionable dune#2399, @emillon)

• Add a new inline_tests field in the env stanza to control inline_tests
  framework with a variable (Adds a new 'inline-tests' setting in env stanza dune#2313, @mlasson, original idea by @diml, review
  by @rgrinberg).

• New binary kind js for executables in order to explicitly enable Javascript
  targets, and a switch (explicit_js_mode) to require this mode in order to
  declare JS targets corresponding to executables. (Explicit js mode dune#1941, @nojb)

Anyone brave enough to merge this? All the failures are see seem to be constraint related
