There is an issue when zephyr is compiled with native_sim_64 where size_t is 8 bytes. The socklen_t in specified as 4 bytes in Linux even for 64 bit builds so we have a conflict between Linux and Zephyr. To make things work properly, define socklen_t as uint32_t in order to align with Linux. Four bytes is enough for socket address length anyway.

This does modify public APIs, do we need some notes? |

Add information that the socklen_t was changed from size_t, which can be either 32 or 64 bit long depending on system configuration, to always be 32 bit long. This is now aligned to way Linux is defining socklen_t. Signed-off-by: Jukka Rissanen <jukka.rissanen@nordicsemi.no>
