Impact: cleanup only, no functionality changed

WARNING: vmlinux.o(.data+0xbe08): Section mismatch in reference from the variable apic_flat to the function .init.text:flat_acpi_madt_oem_check()
The variable apic_flat references
the function __init flat_acpi_madt_oem_check()
This is harmless, because the .acpi_madt_oem_check is only called
during init time. But we keep the function pointer around in a .data
function pointer template, so it's better we do not keep that stale
- so mark this function non-__init.

introducing an APIC handling probing abstraction:
static struct genapic *apic_probe[] __initdata = {
&apic_x2apic_uv_x,
&apic_x2apic_phys,
&apic_x2apic_cluster,
&apic_physflat,
NULL,
};
This way we can remove UV, x2apic specific code from genapic_64.c and
move them to their specific genapic files.

generalize the x2apic code some more.
let read_apic_id become a macro (later on a function/inline)
GET_APIC_ID(apic_read(APIC_ID))
+#define read_apic_id() (GET_APIC_ID(apic_read(APIC_ID)))
instead of this weird construct:
-#define read_apic_id (genapic->read_apic_id)

Introduce a function to read the local APIC_ID.
This change is in preparation for additional changes to
the APICID functions that will come in a later patch.

This patch converts the x86_cpu_to_apicid array to be a per cpu
variable. This saves sizeof(apicid) * NR unused cpus. Access is mostly
from startup and CPU HOTPLUG functions.
MP_processor_info() is one of the functions that require access to the
x86_cpu_to_apicid array before the per_cpu data area is setup. For this
case, a pointer to the __initdata array is initialized in setup_arch()
and removed in smp_prepare_cpus() after the per_cpu data area is
initialized.
A second change is included to change the initial array value of ARCH
i386 from 0xff to BAD_APICID to be consistent with ARCH x86_64.

Remove the x86_cpu_to_log_apicid array. It is set in
arch/x86_64/kernel/genapic_flat.c:flat_init_apic_ldr() and
arch/x86_64/kernel/smpboot.c:do_boot_cpu() but it is never
referenced.
