I'm not sure if we want Qubes patches on aem-next branch? We are/were using this branch for e.g. upstreaming Trenchboot changes. Maybe separate qubes+aem-next branch?

Considering the answer: https://matrix.to/#/!WHWPvnIGPhGGtUFucJ:matrix.org/$Q_vxQEooVvzAs3ienpZNHQ8MMaxdyJ51cybIrmUjDvo?via=matrix.org&via=matrix.tu-berlin.de&via=invisiblethingslab.com, you are right, a separate branch for QubesOS things should be created and the auto-rebase should be run there, not on the aem-next branch.

The only thing that should be changed because of this fact in this PR - are the branches though, all the other things should stay untouched. So we can continue review, but this will be a bloker for the final merge.

Maybe we can use CI variables to specify branches? This way we don't have to hard-code names in commits and can change easily in the future. Although, I'm not sure how often this will change, so it may not be worth it.

# 1. Renaming QubesOS/qubes-vmm-xen/config to
# TrenchBoot/xen/config-qubesos, so it will not conflict with an
# already existing directory "config" in the xen source code.
# 2. Renaming QubesOS/qubes-vmm-xen/xen.spec.in to
# QubesOS/qubes-vmm-xen/vmm-xen.spec.in. This is done because the
# qubes-dom0-packagev2.yml expects the file to have a name
