	* prefix.c: (prefix_ipv4_new, prefix_ipv6_new): Call prefix_new
	  to allocate the memory to make sure that all struct prefix pointers
	  point to objects of the same length (avoids memory overruns
	  on struct prefix assignments).
	  (prefix_ipv4_free, prefix_ipv6_free): Simply call prefix_free.
	  It is interesting to note that these functions are never actually
	  called anywhere in the code.  Instead prefix_free was already
	  being called directly, despite the previous MTYPE incompatibility.
