fix very very insidious bug with mapping physical memory (TLB corruption). fix weirdness reported by michael (underlying cause: using cpu_ClockFrequency instead of wcpu_*; that made the timer run at freq=0)

mahaf: now disabled on Win2k because we can't prevent the TLB bug there.
removed the CopyPhysical API.
wutil: allow querying windows version via number

View: fix warning

This was SVN commit r5169.
