Fix /proc/cpuinfo topology and cache size info

Browse Source 
* 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.
