Further improve the documentation of library initialization and configuration.

Among other improvements:
* Use a uniform wording at the top of the DECSRIPTION for obsolete pages.
* Better explain how to use a non-standard configuration file.
* Remove obsolete functions from SEE ALSO.
Triggered by some suggestions from tb@.
Tweaks and OK tb@.
