The location of the session end hook has been chosen so as it is
possible to allow modules to do their own transactions, however any
trying to any any subsystem which went through before_shmem_exit()
would cause issues, limiting the pluggability of the hook.
Per discussion with Tom Lane and Andres Freund.

Several buildfarm machines have been complaining about the new module
test_session_hooks to be unstable, like crake and thorntail. The issue
was that the module was trying to log some start and end session
activity for parallel workers, which makes little sense as they don't
support DML, so just prevent this pattern to happen in the module.
This could be reproduced by enforcing force_parallel_mode=regress, which
is the value used by some of the buildfarm members.

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.

It's become apparent during testing that there are problems with at
least the testing regime. I don't think we should have it without a
working test regime, and the difficulties might indicate implementation
problems anyway, so I'm backing out the whole thing until that's sorted
out.
