pthread_t is a pointer type on Mac OS X, and is thus 32 bits wide in the 32-bit environment and 64 bits wide in the 64-bit environment. WebRTC's thread ID routines assume that thread IDs can always fit inside a uint32_t, but this is not the case in the 64-bit Mac environment when using pthread_t as the basis for a thread ID. Instead, switch to using the underlying Mach port for the thread, which is a 32-bit quantity in both the 32-bit and 64-bit environments. The only place this seems to be used is in TraceImpl::AddThreadId, and it's only used there for a thread ID for display. This is a better fix than https://webrtc-codereview.appspot.com/929015 .
