tools: add fixup-deprecated.py script to replace deprecated quagga/frr mactors/types...

       Initial deprecated macros are:
	   #define VNL
	   #define VTYNL
	   #define VTY_NEWLINE
	   #define VTY_GET_INTEGER(desc, v, str)
	   #define VTY_GET_INTEGER_RANGE(desc, v, str, min, max)
	   #define VTY_GET_ULONG(desc, v, str)
	   #define VTY_GET_ULL(desc, v, str)
	   #define VTY_GET_IPV4_ADDRESS(desc, v, str)
	   #define VTY_GET_IPV4_PREFIX(desc, v, str)
	   #define vty_outln(vty, str, ...)
