HV:treewide:C99-friendly per_cpu implementation change the per_cpu method

Browse Source 
The current implementation of per_cpu relies on several non-c99 features,
and in additional involves arbitrary pointer arithmetic which is not MIS-
RA C friendly.

This patch introduces struct per_cpu_region which holds all the per_cpu
variables. Allocation of per_cpu data regions and access to per_cpu vari-
ables are greatly simplified, at the cost of making all per_cpu varaibl-
es accessible in files.
