base: Add support for changing output directories
This changeset adds support for changing the simulator output directory. This can be useful when the simulation goes through several stages (e.g., a warming phase, a simulation phase, and a verification phase) since it allows the output from each stage to be located in a different directory. Relocation is done by calling core.setOutputDir() from Python or simout.setOutputDirectory() from C++. This change affects several parts of the design of the gem5's output subsystem. First, files returned by an OutputDirectory instance (e.g., simout) are of the type OutputStream instead of a std::ostream. This allows us to do some more book keeping and control re-opening of files when the output directory is changed. Second, new subdirectories are OutputDirectory instances, which should be used to create files in that sub-directory.
