WL#5154 was a task for formally deprecating and removing items that
were mentioned in the manual as having been deprecated since MySQL
4.1 or 5.0, but that had never been removed.

Since WL#5154 was created, examination of mysqld.cc, mysql.cc, and
mysqldump.c reveals additional deprecations not mentioned in the
manual. (In some cases, the items are simply not mentioned in the
5.1+ manuals.)

This is a follow-on task to deprecate and remove these additional
items.

The deprecation happened in MySQL 5.1, and the options/variables
are now removed from the code.
