All uses of beast::Thread were previously removed from the code base, so beast::Thread is removed. One piece of beast::Thread needed to be preserved: the ability to set the current thread's name. So there's now a beast::CurrentThreadName that allows the current thread's name to be set and returned. Thread naming is also cleaned up a bit. ThreadName.h and .cpp are removed since beast::CurrentThreadName does a better job. ThreadEntry is also removed, but its terminateHandler() is preserved in TerminateHandler.cpp. The revised terminateHandler() uses beast::CurrentThreadName to recover the name of the running thread. Finally, the NO_LOG_UNHANDLED_EXCEPTIONS #define is removed since it was discovered that the MacOS debugger preserves the stack of the original throw even if the terminateHandler() rethrows.
