Use the symbol properties to output the printer/destructor for lalr1.cc.

Browse Source 
Instead of defining complex list of tuples to define various properties of
the symbols, we now prefer to define symbols as "structs" in m4: using the
symbol key (its number), and the property name, b4_symbol gives it value.
Use this to handle destructors and printers.

	* src/output.c (CODE_PROP): New.
	(prepare_symbol_definitions): Use it to define the printer and
	destructor related attributes of the symbols.
	* data/lalr1.cc (b4_symbol_actions): Rename as...
	(b4_symbol_action): this.
	Use b4_symbol instead of 6 arguments.
	(b4_symbol_printer, b4_symbol_destructor): New.
	Use them instead of b4_symbol_actions.
