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.

Limit them to the device_add functionality.  Device aliases were a hack based
on the fact that virtio was modeled the wrong way.  The mechanism for aliasing
is very limited in that only one alias can exist for any device.

We have to support it for the purposes of compatibility but we only need to
support it in device_add so restrict it to that piece of code.

v1 -> v2
 - Use a table for aliases (Paolo)

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
registration functions.

The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.

Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.

We are almost fully converted to QOM after this commit.

These are various small stylistic changes which help make things more
consistent such that the automated conversion script can be simpler.

It's not necessary to agree or disagree with these style changes because all
of this code is going to be rewritten by the patch monkey script anyway.

Implement an I/O space index-data register pair as defined by the AHCI
spec, including the corresponding SATA PCI capability and BAR.

This allows real-mode code to access the AHCI registers; real-mode
code cannot address the memory-mapped register space because it is
beyond the first megabyte.

Fix regression of 667bb59d: ahci_init initializes ahci.mem, so we have to

The commit 667bb59d
uses d->ahci.mem before it is initialized by
ahci_init(). Fix this by calling ahci_init() first thing
so that it's safe to use all fields in the ahci state struct.

Different AHCI controllers have a different number of ports, so the core
shouldn't care about the amount of ports available.

This patch makes the number of ports available to the AHCI core runtime
configurable, allowing us to have multiple different AHCI implementations
with different amounts of ports.

Sebastian's patch already did a pretty good job at splitting up ICH-9
AHCI code and the AHCI core. We need some more though. Copyright was missing,
the lspci dump belongs to ICH-9, we don't need the AHCI core to have its
own qdev device duplicate.

So let's split them a bit more in this patch, making things easier to
read an understand.

There are multiple ahci devices out there. The currently implemented ich-9
is only one of the many. So let's split that one out into a separate file
to stress the difference.
