Optimise ValueLobDB comparison methods

remove unfinished android API

Simplify old lob ValueLob class

to short circuit where possible

remove JaQu

remove STORE_LOCAL_TIME code

This reverts commit c6cf352d.

hmmm, not quite right

Don't try to find tools.jar on Java 9+

was never finished to a degree that anyone was actually using it, can always be resurrected from git

this has been unmaintained for a very long time, mostly because there is an active forked project based on this, so people should rather be using that

this has been hardcoded to false for quite some time now

Do not use deprecated Class.newInstance()

Fix NPE in Parser.parseMergeUsing()

and even then, only in specific situations, so simplify accordingly

and removing them exposes a bug in DataType.getTypeFromClass, which we can't fix right now

clean up some javadoc and some throws clauses

Create UndoLog only when necessary and remove outdated code

Remove some PageStore+MVCC leftovers
