Move the reset of the sysbus (and thus all devices and buses anywhere
on the qbus tree) from qemu_register_reset() to qemu_register_resettable().
This is a behaviour change: because qemu_register_resettable() is
aware of three-phase reset, this now means that:
* 'enter' phase reset methods of devices and buses are called
before any legacy reset callbacks registered with qemu_register_reset()
* 'exit' phase reset methods of devices and buses are called
after any legacy qemu_register_reset() callbacks
Put another way, a qemu_register_reset() callback is now correctly
ordered in the 'hold' phase along with any other 'hold' phase methods.
The motivation for doing this is that we will now be able to resolve
some reset-ordering issues using the three-phase mechanism, because
the 'exit' phase is always after the 'hold' phase, even when the
'hold' phase function was registered with qemu_register_reset().

Reimplement qemu_register_reset() via qemu_register_resettable().
We define a new LegacyReset object which implements Resettable and
defines its reset hold phase method to call a QEMUResetHandler
function. When qemu_register_reset() is called, we create a new
LegacyReset object and add it to the simulation_reset
ResettableContainer. When qemu_unregister_reset() is called, we find
the LegacyReset object in the container and remove it.
This implementation of qemu_unregister_reset() means we'll end up
scanning the ResetContainer's list of child objects twice, once
to find the LegacyReset object, and once in g_ptr_array_remove().
In theory we could avoid this by having the ResettableContainer
interface include a resettable_container_remove_with_equal_func()
that took a callback method so that we could use
g_ptr_array_find_with_equal_func() and g_ptr_array_remove_index().
But we don't expect qemu_unregister_reset() to be called frequently
or in hot paths, and we expect the simulation_reset container to
usually not have many children.

Implement new functions qemu_register_resettable() and
qemu_unregister_resettable(). These are intended to be
three-phase-reset aware equivalents of the old qemu_register_reset()
and qemu_unregister_reset(). Instead of passing in a function
pointer and opaque, you register any QOM object that implements the
Resettable interface.
The implementation is simple: we have a single global instance of a
ResettableContainer, which we reset in qemu_devices_reset(), and
the Resettable objects passed to qemu_register_resettable() are
added to it.

Implement a ResetContainer. This is a subclass of Object, and it
implements the Resettable interface. The container holds a list of
arbitrary other objects which implement Resettable, and when the
container is reset, all the objects it contains are also reset.
This will allow us to have a 3-phase-reset equivalent of the old
qemu_register_reset() API: we will have a single "simulation reset"
top level ResetContainer, and objects in it are the equivalent of the
old QEMUResetHandler functions.
The qemu_register_reset() API manages its list of callbacks using a
QTAILQ, but here we use a GPtrArray for our list of Resettable
children: we expect the "remove" operation (which will need to do an
iteration through the list) to be fairly uncommon, and we get simpler
code with fewer memory allocations.
Since there is currently no listed owner in MAINTAINERS for the
existing reset-related source files, create a new section for
them, and add these new files there also.

We have an OBJECT_DEFINE_TYPE_EXTENDED macro, plus several variations
on it, which emits the boilerplate for the TypeInfo and ensures it is
registered with the type system. However, all the existing macros
insist that the type being defined has its own FooClass struct, so
they aren't useful for the common case of a simple leaf class which
doesn't have any new methods or any other need for its own class
struct (that is, for the kind of type that OBJECT_DECLARE_SIMPLE_TYPE
declares).
Pull the actual implementation of OBJECT_DEFINE_TYPE_EXTENDED out
into a new DO_OBJECT_DEFINE_TYPE_EXTENDED which parameterizes the
value we use for the class_size field. This lets us add a new
OBJECT_DEFINE_SIMPLE_TYPE which does the same job as the various
existing OBJECT_DEFINE_*_TYPE_* family macros for this kind of simple
type, and the variant OBJECT_DEFINE_SIMPLE_TYPE_WITH_INTERFACES for
when the type will implement some interfaces.

Currently the qemu_register_reset() API permits the reset handler functions
registered with it to remove themselves from within the callback function.
This is fine with our current implementation, but is a bit odd, because
generally reset is supposed to be idempotent, and doesn't fit well in a
three-phase-reset world where a resettable object will get multiple
callbacks as the system is reset.
We now have only one user of qemu_register_reset() which makes use of
the ability to unregister itself within the callback:
restore_boot_order(). We want to change our implementation of
qemu_register_reset() to something where it would be awkward to
maintain the "can self-unregister" feature. Rather than making that
reimplementation complicated, change restore_boot_order() so that it
doesn't unregister itself but instead returns doing nothing for any
calls after it has done the "restore the boot order" work.

The nubus-virtio-mmio device is a Nubus card that contains a set of 32 virtio-mmio
devices and a goldfish PIC similar to the m68k virt machine that can be plugged
into the m68k q800 machine.
There are currently a number of drivers under development that can be used in
conjunction with this device to provide accelerated and/or additional hypervisor
services to 68k Classic MacOS.

Whilst 128k is more than enough for a typical Declaration ROM, a C compiler
configured to produce an unstripped debug binary can generate a ROM image that
exceeds this limit. Increase the maximum size to 1Mb to help make life easier
for developers.

Declaration ROM binary images can be any arbitrary size, however if a host ROM
memory region is not aligned to qemu_target_page_size() then we fail the
"assert(!(iotlb & ~TARGET_PAGE_MASK))" check in tlb_set_page_full().
Ensure that the host ROM memory region is aligned to qemu_target_page_size()
and adjust the offset at which the Declaration ROM image is loaded, since Nubus
ROM images are unusual in that they are aligned to the end of the slot address
space.

sysbus_address_space(...) is a simple wrapper to
get_system_memory(). Use it in place, since KVM
VAPIC doesn't distinct address spaces.
Rename the 'as' variable as 'mr' since it is a
MemoryRegion type, not an AddressSpace one.

We want to set another qdev property (a link) for the FIMD
device, we can not use sysbus_create_varargs() which only
passes sysbus base address and IRQs as arguments. Inline
it so we can set the link property in the next commit.
