Get new serialization code to link.

sim/param.cc:
    Convert parseParam() and showParam() to templates,
    andd explicitly instantiate them for common types.
sim/param.hh:
    Add declarations for parseParam() and showParam() function templates,
    so serialize.cc can use them.
sim/serialize.cc:
    Don't need declarations for parseParam() and showParam() since
    we put them in param.hh.
    Also instantiate paramOut() etc. for bool.
