This patch changes how the serialization of the system works. The base class had a non-virtual serialize and unserialize, that was hidden by a function with the same name for a number of subclasses (most likely not intentional as the base class should have been virtual). A few of the derived systems had no specialization at all (e.g. Power and x86 that simply called the System::serialize), but MIPS and Alpha adds additional symbol table entries to the checkpoint. Instead of overriding the virtual function, the additional entries are now printed through a virtual function (un)serializeSymtab. The reason for not calling System::serialize from the two related systems is that a follow up patch will require the system to also serialize the PhysicalMemory, and if this is done in the base class if ends up being between the general parts and the specialized symbol table. With this patch, the checkpoint is not modified, as the order of the segments is unchanged.
