Prevent concurrent calls on the same xHAL connection

Laurent Petre requested to merge bugfix/concurrent-xhal-calls into main

Description

[Based on top of !207 (merged)]

From the commit message:

Until now, no mechanism was put in place to prevent concurrent calls on the same xHAL connection. If forwarded carelessly to the underlying networking layer, the calls can interleave and corrupt the buffers.

A mutex is introduced to serialize the RPC calls and fix the issue.
