Cleaned up OS.h a bit more.

Return type of thread_func is now status_t instead of the previous int32.
Added some more cpuid_info fields - many fields aren't just reserved anymore.
"sysinfo" now supports the extended features of Intel CPUs, and also knows
the "HTT" bit of the standard features indicating the hyper-threading capability.
