The traffic generator currently resolves relative trace paths relative to gem5's current working directory. This can lead to surprising results for relative paths where the expectation would normally be that they are resolved relative to the configuration file. This changeset implements config-relative trace file lookups. The old behavior is kept as a fallback for configs that expect that behavior.
