Allow the cpu_reset_address value to be overridden, for example allowing
it to be a signal. That way the reset address can be modified after
synthesis, in dual-core or debug situations.

In some cases, it can be useful to bind to "0.0.0.0" instead of "localhost".
While adding bind address support, parameters passing has also been refactored
to ease adding parameters in the future.
