WL#5154 Remove deprecated 4.1 features

Several items said to be deprecated in the 4.1 manual
have never been removed.  This worklog adds deprecation
warnings when these items are used, and warns the user 
that the items will be removed in MySQL 5.6.

A couple of previously deprecation decision have been
reversed (see single file comments)
