dc00c828e3 Remove special casing for running in the simulator from the kernel
and instead add platform, firmware and EFI stubs to the loader.
The net effect of this change is that besides a special console and
disk driver, the kernel has no knowledge of the simulator. This has
the following advantages:
o  Simulator support is much harder to break,
o  It's easier to make use of more feature complete simulators.
   This would only need a change in the simulator specific loader,
o  Running SMP kernels within the simulator. Note that ski at this
   time does not simulate IPIs, so there's no way to start APs.

The platform, firmware and EFI stubs describe the following hardware:
o  4 CPU Itanium,
o  128 MB RAM within the 4GB address space,
o  64 MB RAM above the 4GB address space.

NOTE: The stubs in the skiloader describe a machine that should in
parts be defined by the simulator. Things like processor interrupt
block and AP wakeup vector cannot be choosen at random because they
require interpretation by the simulator. Currently the simulator is
ignorant of this.

This change introduces an unofficial SSC call SSC_SAL_SET_VECTORS
which is ignored by the simulator.

Tested with: ski (version 0.943 for linux)

229778f87e o Do not parse the MADT as a side-effect in AcpiOsGetRootPointer,
do it as a side-effect of probing for MP hardware. This allows
   us to scan for local SAPICs early (especially before MBUF
   initialization).
o  Fix the Local SAPIC structure so that matches the Local SAPIC
   table entry. Now that the Local SAPIC info is the same as the
   Local APIC info, stop dumping the Local APIC entries.
o  For every Local SAPIC entry in the MADT that's not disabled,
   let the SMP code know about it. They represent actual CPUs.
o  Register the OS_BOOT_RENDEZ entry point and provide a (bogus)
   implementation for the entry point.
o  Provide a mapping for internal IPI numbers to ExtINT vectors.
o  In a MP system, announce the CPUs and start them by sending
   IPI_AP_WAKEUP to each of them. Not that it makes a difference
   at this time :-)
o  Miscellaneous style fixes and other adjustments.
