* Implement a fairly simplistic parser for unwinding stack frames. * Use unwind records for DDB's 'trace' command. Also add support for tracing past exceptions to the context which generated the exception. The stack unwind code requires a toolchain based on binutils-2.11.2 or later and gcc-3.0.1 or later.
