Serguey Zefirov 2cd8f716c1 Fix MCOL-5035, a difference in INSERT and UPDATE behavior ...

The UPDATE statement wrote NULL when the column set is DATETIME and
value is '0000-00-00 00:00:00'. The problem was inside WriteEngine's
handling of UPDATE statements and this is where heart of change is.

Other changes are related to some obsolete data structures in DML/DDL
handling that just hanging around there, doing nothing.
