suspend: switch acpi s3 to new infrastructure.

This patch switches pc s3 suspend over to the new infrastructure.
The cmos_s3 qemu_irq is killed, the new notifier is used instead.
The xen hack goes away with that too, the hypercall can simply be
done in a notifier function now....

acpi: add ACPIREGS

All those acpi structs are not independent from each other.
Various acpi functions expecting multiple acpi structs passed
in are a clean indicator for that ;)

So this patch bundles all acpi structs in the new ACPIREGS
struct, then use it everythere pass around acpi state....

acpi: don't pass overflow_time to acpi_pm1_evt_get_sts

Pretty pointless, can easily be reached via ACPIREGS now.

qom: Unify type registration

Replace device_init() with generalized type_init().

While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace....

qdev: register all types natively through QEMU Object Model

This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.

The first step was a sed-based addition of the parent type to the subclass...

qdev: move qdev->info to class

Right now, DeviceInfo acts as the class for qdev. In order to switch to a
proper ObjectClass derivative, we need to ween all of the callers off of
interacting directly with the info pointer.

qdev: switch children device list to QTAILQ

SCSI buses will need to read the children list first-to-last. This
requires using a QTAILQ, because hell breaks loose if you just try
inserting at the tail (thus reversing the order of all existing
visits from last-to-first to first-to-tail)....

notifier: Pass data argument to callback

This allows to pass additional information to the notifier callback
