Rebase COLAMD to 3.0.4
    
    This commit replaces Source archive with a repackaged archive without
    colamd/colamd.{c,h} files because of a bad license.
    This commit supplies a new COLAMD 3.0.4 with a different and
    acceptable license using a patch.
    
    It is squashed into a single commit to prevent from leaking the bad
    licensed COLAMD into the patch file.
