Xen3 support [bouyer%NetBSD.org@localhost: CVS commit: src/sys/arch/xen]

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hi,
for those who don't read source-changes.
What's left to do:
1- write block and network front-end for domU kernel
2- write the missing pieces for interrupts and proper PCI support for
  dom0 kernel
3- port xentools30
4- write dom0 kernel support and block and network back-ends.

Log Message:
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.
