Hot Alter Table Support for Automatic System Timestamp

Support for ctdbAlterTable() has been added to include Automatic System Timestamp features. This function can be used to:

  1. Set/reset an existing field to be auto system time
  2. Change the auto system time feature of a field
  3. Add a new field with auto system time
  4. Delete a field with auto system time

During Alter Table, when setting/resetting auto system time, the field content is not modified, i.e., the current timestamp is not applied during Alter Table to existing record contents.
