We need to follow this process: http://incubator.apache.org/ip-clearance/ip-clearance-template.html
Generally, we need: a snapshot of the code (tarball), a Software Grant, and a CLA. The code must have no dependencies on items with licenses incompatible with the ASL. I am a Member of the ASF with Incubator karma so can execute the process assuming we want to do this.
To move forward, we need a snapshot, and since Garrett Wu has already said offline he can represent the copyright holder and is willing to execute a software grant, let's ask him to draw up a software grant (https://www.apache.org/licenses/software-grant.txt) and CCLA (https://www.apache.org/licenses/cla-corporate.txt), if one for Wibi isn't already on file, and submit them to the Apache Secretary (firstname.lastname@example.org)
Once we have a snapshot I can open a new clearance form. Once we have acknowledgement from the Secretary that the Grant and CLA are on file, I can commit the snapshot over at the incubator and start a clearance vote. Assuming that passes, I think we should commit the snapshot as-is on a branch, massage it post commit, then call a branch merge vote to get it into master.
