[lib/memory] Add mallinfo support

2006-02-15 Paul Jakma <paul.jakma@sun.com>

	* configure.ac: Check for mallinfo, being careful to link test
	  so we can detect things like umem being used (which doesn't
	  provide a mallinfo).
	* lib/memory.c: (mtype_memstr) new helper function to
	  return human friendly string for a byte count.
	  (mtype_stats_alloc) new function, for users to retrieve
	  number of objects allocated.
	  (show_memory_mallinfo) New function, show mallinfo statistics
	  if available.
	  (show_memory_all_cmd) Call show_memory_mallinfo, if mallinfo
	  is available.
	* lib/memory.h: Export mtype_memstr and mtype_stats_alloc.
	  Provide a define for a reasonable buffer size for
	  mtype_memstr.
