	BOOL SetNVProtection(STRPTR, STRPTR, LONG, BOOL);

   FUNCTION
	Sets the protection attributes for an item currently in the
	nonvolatile storage.

	Although 'mask' is LONG only the delete bit, NVEF_DELETE/NVEB_DELETE,
	may be set. If any other bits are set this function will return
	FALSE.

	The strings appName and itemName may not contain the '/' or ':'
	characters. It is recommended that these characters be blocked
	from user input when requesting AppName and ItemName strings.

	appName - NULL terminated string indicating the application name
		  to be matched. Maximum length is 31.
	itemName - NULL terminated string indicated the item within the
		   application to be found. Maximum length is 31.
	mask - the new protection mask. Only set the delete bit otherwise
	       this function WILL CRASH.
	killRequesters - suppress system requesters flag. TRUE if all system
			 requesters are to be suppressed during this function.
			 FALSE if system requesters are allowed.

   RESULT
	success - FALSE if the protection could not be change (ie the data
		  does not exist).
