add prototypes for the _change* functions.

2002-10-24  Chris Toshok  <toshok@ximian.com>

	* e-table-memory-store.h: add prototypes for the _change*
	functions.

	* e-table-memory-store.c (e_table_memory_store_change_array): new
	function, mostly c&p from _insert_array.
	(e_table_memory_store_change): new function, mostly c&p from
	_insert.
	(e_table_memory_store_change_adopt_array): new function, mostly
	c&p from _insert_adopt_array.
	(e_table_memory_store_change_adopt): new function, mostly c&p from
	_insert_adopt.
