Previously, StartHandler() launched the handler process, then connected over a pipe to register for crash handling. Instead, the initial client can create and inherit handles to the handler and pass those handle values and other data (addresses, etc.) on the command line. This should improve startup time as there's no need to synchronize with the process at startup, and allows avoiding a call to CreateProcess() directly in StartHandler(), which is important for registration for crash reporting from DllMain(). Incidentally adds new utility functions for string/number conversion and string splitting. Note: API change; UseHandler() is removed for all platforms.
