Subject: qom: Introduce CPU class
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reintroduce CPUState as QOM object: It's abstract and derived directly
from TYPE_OBJECT for compatibility with the user emulators.
The identifier CPUState avoids conflicts between CPU() and the struct.

Introduce $(qom-twice-y) to build it separately for system and for user
emulators.

Prepare a virtual reset method, (re)introduce cpu_reset() as wrapper.
