Fix /proc/cpuinfo topology and cache size info
* autoload.cc (GetLogicalProcessorInformationEx): Import.
(SetThreadGroupAffinity): Import.
* fhandler_proc.cc (add_size): New macro.
(get_msb): New inline function.
(mask_bits): Ditto.
(format_proc_cpuinfo): Drop handling of old CPUs. Check if we're
running on a OS version supporting porcessor groups. If so, use
SetThreadGroupAffinity to set thread affinity. Improve cache info
to include 3rd level cache on Intel CPUs. Improve multi core info.
* wincap.h (wincaps::has_processor_groups): New element.
* wincap.cc: Implement above element throughout.
