This is done to create a PEP420 namespace package, in which we may create subpackages. To do this, the namespace directory ("qemu") should not have any modules in it. Those files will go into new 'machine' and 'qmp' subpackages instead. Implement machine/__init__.py making the top-level classes and functions from its various modules available directly inside the package. Change qmp.py to qmp/__init__.py similarly, such that all of the useful QMP library classes are available directly from "qemu.qmp" instead of "qemu.qmp.qmp". Signed-off-by: John Snow --- Note for reviewers: in the next patch, I add a utils sub-package and move qemu/machine/accel.py to qemu/utils/accel.py. If we like it that way, we can squash it in here if we want, or just leave it as its own follow-up patch, I am just leaving it as something that will be easy to un-do or change for now.
