Bug #19498: Inconsistent support for DEFAULT in TEXT columns

Browse Source 
When a default of '' was specified for TEXT/BLOB columns, the specification
  was silently ignored. This is presumably to be nice to applications (or
  people) who generate their column definitions in a not-very-clever fashion.

  For clarity, doing this now results in a warning, or an error in strict
  mode.

  Issue a warning when setting '' as the default on a BLOB/TEXT column,
  and make it an error in strict mode. Also, clarify comments about when
  NO_DEFAULT_VALUE_FLAG is set.
