My plan for this is to only put directories in include/, which limits a
lot the possibility of confusion, for example

#include <exec/cpu-all.h>
#include <qapi/qapi-types.h>

etc.

Unfortunately, this _does_ require touching every .c file.

I disagree about qemu/ vs. other directories, but yes, it is better to
avoid touching .c files at the same time you're moving them.

It is not completely possible, mostly because some header files in net/
combine both private content (which should move to sysemu/net/) and
public content (which should move to include/net/), but that should be
the exception.
