Commit Message

ModifyColumn.Unsafe(): Whitelist more safe type changes

Previously, the following column type changes were unnecessarily marked as
unsafe:

* char(x) -> varchar(y), y >= x
* varchar(x) -> char(y), y >= x
* char(x) -> *text, where new text type max >= x
* varchar(x) -> *text, where new text type max >= x
* *text -> char(x), where x >= old text type max
* *text -> varchar(x), where x >= old text type max
* varbinary(x) -> *blob, where new blob type max >= x
* *blob -> varbinary(x), where x >= old blob type max
* bit(x) -> bit(y), y >= x
* *int unsigned -> *int, where new int type is strictly larger than old int
  type
* removing unsigned attribute from a float, decimal, or double (without
  otherwise reducing size)

All of these cases have no possibility of data loss, so they are now correctly
considered safe changes.
