        src/sys/sys: kcpuset.h

Log Message:
- Convert x86 MD code, mainly pmap(9) e.g. TLB shootdown code, to use
  kcpuset(9) and thus replace hardcoded CPU bitmasks.  This removes the
  limitation of maximum CPUs.

- Support up to 256 CPUs on amd64 architecture by default.

Bug fixes, improvements, completion of Xen part and testing on 64-core
AMD Opteron(tm) Processor 6282 SE (also, as Xen HVM domU with 128 CPUs)
by Manuel Bouyer.
