[!!!][TASK] Remove RDCT redirect functionality

The very legacy RDCT code and the corresponding DB table
"cache_md5params" has been long superseeded and is be
completely moved into its own extension "RDCT" published
on GitHub https://github.com/FriendsOfTYPO3/rdct and in TER.

An upgrade wizard checks if the DB table is filled,
and then installs EXT:rdct.

Note #1: I decided to trigger the hard breaking way,
instead of deprecation as the whole logic (evalution,
static method call in GeneralUtility removed) is interconnected
and only makes sense if all places are there.

Note #2: This functionality has not been in use in the
TYPO3 Core since 4.x - at all, but is in place for
other extensions.
