CVP13 register access compatibility

Laurent Petre requested to merge feature/cvp13-memhub into main


This MR aims at adding the CVP13 compatibility in the memhub library. In order to achieve such a goal, the memhub library was re-written from scratch, with both a server and client part.

The server, running as a privileged user, is in charge of sending a file descriptor to the underlying memory to a non-privileged user via a UNIX domain socket.

The memhub client is a library that can be used to fetch the open file descriptor from the server. It maps the physical memory into the virtual address space and arbitrates the register accesses.
