Change signal, uncaught NSExceptions and Mach exception handlers to prevent re-entrancy with a first-exception-wins approach to prevent concurrent exceptions from trying to use the same cached intermediate dump writer. Uses compare-and-swap to either return early for reentrant signals or to wait indefinitely for anything after the first fatal exception. Change the NSException handler generated from the Objective-C exception preprocessor to not used the cached intermediate dump writer and not use the same first-exception-wins logic. This is useful because the Objective-C exception preprocessor is imperfect and may generate intermediate dumps that are not followed by process termination. Simplify DumpWithoutCrashing's ownership of its intermediate dump writer to be thread safe. Set a handler for SIGPIPE for applications that haven't already ignored or set a handler for SIGPIPE.
