Stop using "deprecated and ignored"

Many InnoDB system variables have changes described as "deprecated and ignored". A correct description would be parsed but ignored.

The usage of "deprecated" within MySQL and within IT in general is for features that are still supported but will likely be removed in a future release – deprecation is step 1, removal is step 2. But MariaDB combines these into one step, and even worse – parses and ignores them to make upgrades easier but leading to my.cnf settings that don't do what you expect them to do.

So my request is to stop using "deprecated and ignored". You are welcome to use "parsed but ignored" although I am also not a fan of that because MySQL already has a way to safely do "parse but ignored" via the "loose_" prefix
