 MC:
  - Rework the internals, for simpler and modern code. This shall unlock many future improvements.
- - You can now define plugins onto SafetyChecker (a simple DFS explorer), using the declared signals.
-   See CommunicationDeterminism for an example.

  - Support mutex, semaphore and barrier in DPOR reduction
  - Seems to work on Arm64 architectures too.
  - Display a nice error message when ptrace is not usable.

  - Reimplementation of barriers natively. 
    Previously, they were implemented on top of s4u::Mutex and s4u::ConditionVariable. 
    The new version should be faster (and can be used in the model-checker).
