    Patch 044 migration to work w/ MySQL 5.6

    With MySQL 5.6 setup to use UTF-8 for everything, the 044 migration
    will fail. This is because a VARCHAR(256) cannot be indexed in UTF-8
    databases. In versions of MySQL before 5.6, this produced a warning and
    a truncated, less-useful index. In 5.6 it was changed to an error.

    We will reduce these columns further to 64 bytes in the model in a
    subsequent fix. For now, we will just create the table with 64 character
    columns on new systems, which will allow this migration to work properly
    on mysql-5.6. There is no danger of overflow, as 64 chars is what Keystone
    uses for them anyway.
