Add walreceiver API to get remote server version

Enterprise / PostgreSQL - Peter Eisentraut [eisentraut.org] - 15 March 2019 09:16 EDT

Add a separate walreceiver API function walrcv_server_version() to get the version of the remote server, instead of doing it as part of walrcv_identify_system(). This allows the server version to be available even for uses that don't call IDENTIFY_SYSTEM, and it seems cleaner anyway.

This is for an upcoming patch, not currently used.
