iox-#2301 Mixed mode 32 and 64 bit

[elBoberido]

Notes for Reviewer

This PR enables to connect 32 and 64 bit applications to have zero-copy communication. It is currently a technology preview based on spin locks and spin semaphores as replacement for their POSIX counterpart. For production, these contructs need to be based on futex on Linux and WaitOnAddress on Windows. For other OSes, solutions need to be found as well.
