These IRQ counting functions will soon be required in binaries that
do not include the APIC code, too, so let's extract them into a
separate file that can be linked independently of the APIC code.
While we're at it, change the apic_* prefix into kvm_* since the
functions are used from the i8259 PIC (i.e. not the APIC), too.

Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.
Patch generated using:
$ ./scripts/codeconverter/converter.py -i \
--pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')
which will split "typdef struct { ... } TypedefName"
declarations.
Followed by:
$ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
$(git grep -l '' -- '*.[ch]')
which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

Remove the need to include i386/pc.h to get to the i8259 functions.
This is enough to remove the inclusion of hw/i386/pc.h from all non-x86
files.

In my "build everything" tree, changing hw/irq.h triggers a recompile
of some 5400 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).
hw/hw.h supposedly includes it for convenience. Several other headers
include it just to get qemu_irq and.or qemu_irq_handler.
Move the qemu_irq and qemu_irq_handler typedefs from hw/irq.h to
qemu/typedefs.h, and then include hw/irq.h only where it's still
needed. Touching it now recompiles only some 500 objects.

The function has been deprecated for 2.5 years, and there are just a handful
of users. Convert them to memory_region_init_io with NULL callbacks,
and while at it pass the right device as the owner.

Let's leverage the i8259 common code for kvm-i8259 too.
I think it's still possible that stats can lost when i8259 is in kernel
and meanwhile when irqfd is used, e.g., by vfio or vhost devices.
However that should be rare IMHO since they should be using MSIs mostly
if they really want performance (that's why people use vhost and device
assignment), and no old INTx should be used. As long as the INTx users
are emulated in QEMU the stats will be correct.
For "info pic", it should be always accurate since we fetch kvm regs
before dump.
More importantly, it's just too simple to do this now - it's only 10+
LOC to gain this feature.

Instead of having the parent provide PICCommonClass::init,
let the children override DeviceClass::realize themselves.
This pushes the responsibility of saving and calling the parent's
realizefn to the children.
