remove 'vers_auto_decrement'

Browse Source 
Do not generate fake values when adding an auto-inc column to a versioned
table. This is not a auto-inc issue, but a more general case of adding
a not nullalble unique column to a table with history. We don't support
it yet, not even with a special auto-inc hack. As a workaround, one
can use a nullable unique column, that works.
