Summary: The list of fields of a Java object in SIL is the list of fields declared in the class plus all the fields declared in the the super classes. It turns out that we were missing the fields declared in the implemented interfaces.

Summary:
Calling `Exn.backtrace` doesn't give us the current backtrace, only the one of
the latest exception raised. Change the logic of toplevel exception catching to
print the right backtrace.
Also, do not use `Format` to print from `Config` as `Logging` may have messed
with it already.
Finally, throw in some colours!

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.

When a lambda has an `auto` parameter, the inferred type of the parameter because part of the name.
Our heuristic for identifying lambda was checking if the lambda's name was exactly `operator()`, which won't catch this case.

- Introduce the `SimpleLogging` module for dying from modules where `Logging`
cannot be used (usually because that would create a cyclic dependency).

Summary:
This approach was requiring the `InferArray` class to always be part of the classpath, and the only benefit was to preserve the length of the arrays, when known, on calls to `clone()` method. However, adding it to the models would create circular dependencies between the models, the builtins and the tests.
The code is now simpler and we can more aggressively fail when classes that are supposed to be found from the classpath are not found.
