Add session_preload_libraries configuration parameter
This is like shared_preload_libraries except that it takes effect at
backend start and can be changed without a full postmaster restart. It
is like local_preload_libraries except that it is still only settable by
a superuser. This can be a better way to load modules such as
auto_explain.
Since there are now three preload parameters, regroup the documentation
a bit. Put all parameters into one section, explain common
functionality only once, update the descriptions to reflect current and
future realities.
