Doug Rabson d57b94ba65 * Factor out common code for manipulating the RSE backing store.
* 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.
