Add hooks for session start and session end, take two

Enterprise / PostgreSQL - Michael Paquier [paquier.xyz] - 1 October 2019 03:15 EDT

These hooks can be used in loadable modules. A simple test module is included.

The first attempt was done with cd8ce3a but we lacked handling for NO_INSTALLCHECK in the MSVC scripts (problem solved afterwards by 431f1599) so the buildfarm got angry. This also fixes a couple of issues noticed upon review compared to the first attempt, so the code has slightly changed, resulting in a more simple test module.
