[PATCH v3 00/10] fhandler_proc.cc(format_proc_cpuinfo): fix issues, add fields, feature flags

[Brian Inglis <Brian dot Inglis at SystematicSW dot ab dot ca>]

*   fix cache size return code handling and make AMD/Intel code common
*   fix cpuid level count as number of non-zero leafs excluding sub-leafs
*   fix AMD physical cores count documented as core_info low byte + 1
*   round cpu MHz to correct Windows and match Linux cpuinfo
*   add bogomips which has been cpu MHz*2 since Pentium MMX
*   add microcode from Windows registry Update Revision REG_BINARY
*   feature test print macro makes cpuid feature, bit, and flag text
    comparison and checking easier;
    handle as common former Intel only feature flags also supported on AMD;
    change order and some flag names to agree with current Linux
*   add 99 feature flags inc. AVX512 extensions, AES, SHA with 20 cpuid calls
*   comment out flags not reported by Linux in cpuinfo although some flags
    may not be used by Linux
*   or model extension bits into high model bits instead of adding
    arithmetically like family extension bits
