	* (global) more const'ification.
	* sockunion.c: (sockunion_su2str) buffer should be sized
          SU_ADDRSTRLEN.
          (sockunion_log) do not return stack variables, strdup buf before
          return.
        * vty.h: Fix up the VTY_GET_INTEGER macros. Testing caller supplied
          values against ULONG_MAX is daft, when caller probably has passed
          a type that can not hold ULONG_MAX. use a temporary long instead.
          Add VTY_GET_LONG, make VTY_GET_INTEGER_RANGE use it, make
	  VTY_GET_INTEGER a define for VTY_GET_INTEGER_RANGE.
