_cpuid() - full cpuid instruction wrapper
...
- the prototype changes to
_cpuid(u32_t *eax, u32_t *ebx, u32_t *ecx, u32_t *edx)
- this makes possible to use all the features of the cpuid instruction as
described in the Intel specs

Local APIC
...
- local APIC timer used as the source of time
- PIC is still used as the hw interrupt controller as we don't have
enough info without ACPI or MPS to set up IO APICs
- remapping of APIC when switching paging on, uses the new mechanism
to tell VM what phys areas to map in kernel's virtual space
- one more step to SMP
based on code by Arun C.

Library call for cpu features; make kernel and vm use this to query cpu

features (specifically: 4MB pages and TLB global bit). Only enable
these features in CR4 if available. 4MB pages to be used in the near
future.
