Remove bitrotted xen specific versions of pci, pciide machdep related code.

Use the common x86/ code instead.

Retire xen/x86/intr.c and use the new xen specific glue in x86/x86/intr.c

The purpose of this change is to expose the x86/include/intr.h API
to drivers. Specifically the following functions:

   void *intr_establish_xname(...);
   void *intr_establish(...);
   void intr_disestablish(...);

while maintaining the old API from xen/include/evtchn.h, specifically
the following functions:

    int event_set_handler(...);
    int event_remove_handler(...);

This is so that if things break, we can keep using the old API until
everything stabilises. This is a stepping stone towards getting the
actual XEN event callback path rework code in place - which can be
done opaquely behind the intr.h API - NetBSD/XEN specific drivers that
have been ported to the intr.h API should then work without
significant further modifications.

Neither pci_dma64_available(), pci_probe_device(), pci_mapreg_map(9),
pci_find_rom(), pci_intr_map(9), pci_enumerate_bus(), nor the match
predicate passed to pciide_compat_intr_establish() should ever modify
their pci_attach_args argument, so make their pci_attach_args arguments
const and deal with the fallout throughout the kernel.

For the most part, these changes add a 'const' where there was no
'const' before, however, some drivers and MD code used to modify
pci_attach_args.  Now those drivers either copy their pci_attach_args
and modify the copy, or refrain from modifying pci_attach_args:

Xen: according to Manuel Bouyer, writing to pci_attach_args in
    pci_intr_map() was a leftover from Xen 2.  Probably a bug.  I
    stopped writing it.  I have not tested this change.

siside(4): sis_hostbr_match() needlessly wrote to pci_attach_args.
    Probably a bug.  I use a temporary variable.  I have not tested this

slide(4): sl82c105_chip_map() overwrote the caller's pci_attach_args.
    Probably a bug.  Use a local pci_attach_args.  I have not tested
    this change.

viaide(4): via_sata_chip_map() and via_sata_chip_map_new() overwrote the
    caller's pci_attach_args.  Probably a bug.  Make a local copy of the
    caller's pci_attach_args and modify the copy.  I have not tested
    this change.

While I'm here, make pci_mapreg_submap() static.

With these changes in place, I have tested the compilation of these

When ioapic is used, for ISA interrupts, reuse the legacy ISA interrupt
number instead of allocating a new one. Force allocating a new interrupt number
for PCI devices, as the number stored in the PCI interrupt register
may be wrong.
This should help using a pciide controller in compat mode or ISA devices
in a non-0 domain.

Add Xen3 support for ACPI and/or MPBIOS + IOAPIC. To help with this, physical
CPUs are now configured on mainbus only in dom0, and only to know about
their APIC id. virtual CPUs are attached to hypervisor as:
vcpu* at hypervisor?
and this is what's used as curcpu(). The kernel config files needs to be
updated for this, see XEN3_DOM0 or XEN3_DOMU for examples.
XEN3_DOM0 now has acpi, MPBIOS and ioapic by default.
Note that a Xen dom0 kernel doens't have access to the lapic.

Snapshot of work in progress on NetBSD port to Xen3:
- kernel (both dom0 and domU) boot, console is functionnal and it can starts
  software from a ramdisk
- there is no driver front-end expect console for domU yet.
- dom0 can probe devices and ex(4) work when Xen3 is booted without acpi
  and apic support. But the on-board IDE doens't get interrupts.
  The PCI code still needs work (it's hardcoded to mode 1). Some of this
  code should be shared with ../x86
  The physical insterrupt code needs to get MPBIOS and ACPI support, and
  do interrupt routing to properly interract with Xen.
To enable Xen-3.0 support, add
options XEN3
to your kernel config file (this will disable Xen2 support)
Changes affecting Xen-2.0 support (no functionnal changes intended):
- get more constants from genassym for assembly code
- remove some unneeded registers move from start()
- map the shared info page from start(), and remove the pte = 0xffffffff hack
- vector.S: in hypervisor_callback() make sure %esi points to
  HYPERVISOR_shared_info before accessing the info page. Remplace some
  hand-written assembly with the equivalent macro defined in frameasm.h
- more debug code, dissabled by default.

Get rid of the event to pseudo-irq mapping. We are limited to 32 pseudo-irq,
including soft interrupt, and this is way too low in some use (lots of domains,
or domains with lots of xennet, or even hardware with lots of devices at
different interrupts).
Based on idea from YAMAMOTO Takashi, keep one list of handler per-event and
one per-IPL (so the same handler is now in 2 lists). In the common case were
an event is received at low IPL, we can call the handlers quickly (there
is usually only one handler per event, unless the event is mapped to a
physical interrupt and this interrupt is shared by different devices).
Deffered events and software interrupts are handled by a bitmask (as before)
with one bit per IPL. When one IPL has an event pending all handlers for
this IPL will be called.
With this change, it is now possible to have all the 1024 events active.

While here, handle debug event in a special way: the handler is always called,
regardless of the current IPL. Make the handler print usefull informations
about events and IPL states.
Also remove code not used on Xen in files inherited from the x86 port.
