Collapse most column diffing to single loop & single ALTER TABLE
Test that multiple column adds/drops are collapsed to the same ALTER TABLE
UPDATE columns directly with default value where possible
Simplify column creation
Add comment explaining changes to mysql5_diff_tables::update_table_columns
Conditionally include AUTO_INCREMENT flags in table diff output
Reflect column oldName changes from commit 5396231
Aggregate constraint modifications into single ALTER TABLE
Drop AUTO_INCREMENT just before dropping PKs, add it just after adding PKs
A test to get working eventually in the future
