In general, it's a good idea to make headers self-contained by
recursively including whatever's necessary.
However, there are a few very central headers that are just too
complicated to make self-consistent without introducing circular references.
In particular, for QEMU these are qemu-common.h and cpu.h (and also
others, such as exec-all.h but perhaps the solution there is to split
them). It's much simpler to ask people to include these two files in
the C files.
