Summary:
Main changes are:
1. Dune can promote targets into the source tree as a part of build. This
allows us to **remove custom promotion/installation logic in src/Makefile**.
2. Dune promotion only works for path within workspace. This required
**moving dune-workspace one folder up**: from infer/infer/src to infer/infer.
But this is not bad, since it makes it possible to migrate tests under dune at some point.
3. `checkCopyright` now also promoted into `infer/infer/bin` instead of
`infer/scripts` partly for consistency and partly because of the
dune-workspace location.
4. `byte` mode was replaced with `byte_complete`. The latter takes
similar amount of time to build compared to `byte`, but produces
standalone binaries that don't require InferCStubs to be
installed. This allowed to remove `dune_exec_shim` and custom logic
around `dune build InferCStubs.install` when dealing with byte
targets.
All in all, `infer/src/Makefile` is not about 2/3 its previous size
with less custom logic in Makefiles/scripts and more encoded in dune
build files.

Summary:
With the introduction of environments and profiles we no longer need
to generate most dune files in libraries via make. Also, those dune
builds don't need to be in OCaml.
In addition to converting build files to plain sexp definitions, this
patch also:
- Adjusts copyrightCheck to work correctly with sexp-based dune files.
- Adds auto-formatting for sexp-based dune files.

Summary:
Switches from opam 1 to opam 2.
Opam2 has some cool new features that simplify some of the scripting.
Notable changes:
1. Use the new `opam lock` *plugin* from https://github.com/AltGr/opam-lock/ instead of https://github.com/rgrinberg/opam-lock. This has a simpler interface for our purposes.
2. Change the way `./build-infer.sh` can be called to use an already existing switch: simply pass `--user-opam-switch` to the script and it won't attempt to create/set the current switch. This can be used to build infer in a local switch for instance.
3. Take advantage of automatic pinning where possible, eg to install infer deps without using opam.locked.

Summary:
Some paths are hardcoded in infer as being relative to the current executable,
for instance the directory where to find the models. By copying infertop.bc to
infer/bin like we do for `infer` these relative paths lead to the expected
place, which means models can be loaded in the toplevel like they would be in a
normal infer execution. This is more useful for debugging than previously.

Summary:
There's actually a nice separation between IR/, base/, istd/, and the rest of
infer, so they can be made into separate jbuilder libraries so that the
separation remains. This helps make sense of the infer codebase.
Also:
- move everything biabduction-related out of backend/ and into a new
biabduction/ directory. This clarifies the current situation where backend/
contains a mix of analysis-independent code (still there now), and
biabduction-specific code (moved to biabduction/).
- move everything from base/ that is not infer-specific into istd/, e.g. IList.ml
- kill unused `FbTraceCalls`
- A couple of files needed to move around to complete the separation of base/ and IR/

Summary:
Record the db schema, infer version, and run dates into
infer-out/.infer_runstate.json. This allows us to check on startup whether the
results directory was generated using a compatible version of infer or not, and
give a better error message in the latter case than some SQLite error about
mismatching tables.
This will be used in a follow-up diff to record capture phases too, and avoid
relying on filesystem timestamps of the infer-out/capture/foo/ directories for
reactive analysis.
Had to change some tests Makefiles to make sure they do not attempt to re-use
stale infer-out directories, which would now fail the run.
The stale infer-out directory gets deleted if `--force-delete-results-dir` is
passed (but a warning still gets printed).

Summary:
Installing with `opam pin` risks upgrading a lot of package in the current
switch, which is very slow. It's also wasted work since we'll install back
their older versions afterwards with `opam lock`. Moreover, that second step
can now fail if javalib needs to be recompiled (which it seems it does),
because we delete the javalib sources after having pinned them.
Solution: 1. do not install javalib at `opam pin` time, and 2. do not remove its source tree after pinning.

Menu:
1. Write a jbuild file, autogenerated from jbuild.in because we need to fill in
some information at build-time (really, at configure time, but TODO), such as
whether or not clang is enabled.
2. Nuke lots of stuff from infer/src/Makefile that is now in the jbuild file
3. The jbuild file lives in infer/src/ so it can see all the sources. If we put it somewhere else, eg, infer/, then `jbuilder` scans too many files (all irrelevant) and takes 2.5s to start instead of .8s. Adding irrelevant directories to jbuild-ignore does not help.
4. jbuilder does not support subdirectories, so resort to listing all the
source files in the generated jbuild (only source directories need to be
manually listed in jbuild.in though). Still, the generated .merlin is wrong
and makes merlin find source files in _build, so manually tune it to get
good merlin support. We also lose some of merlin for unit tests as it
cannot see their build artefacts anymore.
5. checkCopyright gets its own jbuild because it's standalone. Also, remove
some deprecation warnings in checkCopyright due to the new version of Core from
a while ago.
6. Drop less-used Makefile features (they had regressed anyway) such as
building individual modules. Also, building mod_dep.pdf now takes all the
source files available so they better build (before, it would only take the
source files from the config, eg with or without clang) (that's pretty minor).
7. The toplevel is now built as a custom toplevel because that was easier. It
should soon be even easier: https://github.com/janestreet/jbuilder/issues/210
8. Move BUILTINS.mli to BUILTINS.ml because jbuilder is not happy about
interface files without implementations.
In particular, I did not try to migrate too much of the Makefile logic to jbuilder,
more can be done in the future.

By default the two build commands are the same. If the script is to be used for both the current and the previous versions, then it's on the user to run it once first, eg:
