Indicate to the {@link PdbAddressManager} that a new symbol with the given name has the
associated address.  This allows the PdbAddressManager to create and organize the
re-mapped address and supply them.  Also returns the address of the pre-existing symbol
of the same name if the name was unique, otherwise null if it didn't exist or wasn't
unique.
@param name the symbol name
@param address its associated address
@return the {@link Address} of existing symbol or null
