    Add table for files in merge request diffs · 9a73b634
    Sean McGivern authored
    This adds an ID-less table containing one row per file, per merge request
    diff. It has a column for each attribute on Gitlab::Git::Diff that is serialised
    currently, with the advantage that we can easily query the attributes of this
    new table.
    
    It does not migrate existing data, so we have fallback code when the legacy
    st_diffs column is present instead. For a merge request diff to be valid, it
    should have at most one of:
    
    * Rows in this new table, with the correct merge_request_diff_id.
    * A non-NULL st_diffs column.
    
    It may have neither, if the diff is empty.
