[RFC v4 0/9] i386 cleanup

[Claudio Fontana]

Hi all, this is v4 of the i386 cleanup,
with the most interesting patches at the end.

v3 -> v4: QOMification of X86CPUAccelClass

In this version I basically QOMified X86CPUAccel, taking the
suggestions from Eduardo as the starting point,
but stopping just short of making it an actual QOM interface,
using a plain abstract class, and then subclasses for the
actual objects.

Initialization is still using the existing qemu initialization
framework (module_call_init), which is I still think is better
than the alternatives proposed, in the current state.

Possibly some improvements could be developed in the future here.
In this case, effort should be put in keeping things extendible,
in order not to be blocked once accelerators also become modules.

Motivation and higher level steps:

Looking forward to your comments on this proposal,

Ciao,

Claudio
