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. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14533 a95241bf-73f2-0310-859d-f6bbb57e9c96
