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.

Subject: [PATCH 2/2] Port lp_MDO to colamd-3.0.4
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
The port was done intentionally without modifying the COLAMD sources.
|
||||
That should ease any future rebases, or building against
|
||||
a system-provided COLAMD library.
