core: bye bye sat_tmp :)

After 11 years of "temporary" monkey patches, I've finally made a friendly fork of Wokkel
at https://www.goffi.org/forge/goffi/tx-xmpp with all needed PRs merged and changes from
`sat_tmp`, using the same license as Wokkel (with agreement from contributors). No more
monkey patching, and it will also stop the deprecation warning due to outdated packages
used in Wokkel. Last but not least, it should unblock the move to the latest Twisted and
Python versions.
