debugcommands: introduce standalone module for debug commands
commands.py is our largest .py file by nearly 2x. Debug commands live
in a world of their own. So let's extract them to their own module.
We start with "debugancestor."
We currently reuse the commands table with commands.py and have a hack
in dispatch.py for loading debugcommands.py. In the future, we could
potentially use a separate commands table and avoid the import of
debugcommands.py.
