Summary:
Kill java_stubs/ with this one easy trick:
- java/dune contains either the "normal" modules or just the
JavaFrontendStubs module
- libraries that depend on java need to open JavaFrontendStubs if java
is disabled to bring the expected modules from java/ into their
namespace
Also needed to move biabduction/Prover.Subtyping_check to
absint/SubtypingCheck because the Java frontend was using it.

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 profiles and `(env ...)` stanza it's possible to consolidate
various ocamlc/ocamlopt/etc setups in a single place.
Where previously we needed to append `dune.common` to every dune file
and specify `flags` and `ocamlopt_flags` now the flags are specified
in `env` and applied accross the board.
This allows to
1. simplify build definitions,
2. avoid the need to generate dune files,
3. use plain sexps instead of OCaml and JBuilder plugin in build
files.
(I'll try to address 2 and 3 in the followup patches).
Existing `make` targets should continue working as before. Also, we
can use dune CLI like so:
```
infer/src$ dune printenv --profile opt # <- very useful for introspection
infer/src$ dune build check
infer/src$ dune build check --profile test
infer/src$ dune build infer.exe --profile dev
infer/src$ dune build infer.exe --profile opt
```
Also, with just 1 context something like `dune runtest` will run unit
tests only once instead of N times, where N is the number of contexts.
Now, there's one difference compared to the previous setup with
contexts:
- Previously, each context had its own build folder, and building infer
in opt context didn't invalidate any of the build artifacts in default
context. Therefore, alternating between `make` and `make opt` had low
overhead at the expense of having N copies of all build artifacts (1
for every context).
- Now, there's just 1 build folder and switching between profiles does
invalidate some artifacts (but not all) and rebuild takes a bit more
time.
So, if you're alternating like crazy between profiles your experience
may get worse (but not necessarily, more on that below). If you want
to trigger an opt build occasionally, you shouldn't notice much
difference.
For those who are concerned about slower build times when alternating
between different build profiles, there's a solution: [dune
cache](https://dune.readthedocs.io/en/stable/caching.html).
You can enable it by creating a file `~/.config/dune/config` with the
following contents:
```
(lang dune 2.0)
(cache enabled)
```
With cache enabled switching between different build profiles (but
also branches and commits) has ~0 overhead.
Dune cache works fine on Linux, but unfortunately there are [certain
problems with
MacOS](https://github.com/ocaml/dune/issues/3233) (hopefully, those
will be fixed soon and then there will be no downsides to using
profiles compared to contexts for our case).

Summary:
We inline the .ml and the .mli together using the .cmi rule (for reasons
explained in the Makefile of deadcode). This relies on the fact that rules will
start from the .cmx, which in turns depends on the .cmi as the last dependency
and so all the dependencies of the .cmx are satisfied by the time we hit the
.cmi. But that doesn't always work.
For some reason, making the .cmi depend on its .cmx works, even though it's
supposed to include a circular dependency (`make` should complain but doesn't).

contains a mix of analysis-independent code (still there now), and
biabduction-specific code (moved to biabduction/).

- kill unused `FbTraceCalls`
