Not Zed 24b06cb2a4 Use a bag instead of a hashtable to track the cache streams. 
2002-12-07  Not Zed  <NotZed@Ximian.com>

	* camel-data-cache.c (data_cache_init): Use a bag instead of a
	hashtable to track the cache streams.
	(data_cache_finalise): Same.
	(free_busy): No longer needed.
	(data_cache_expire): use bag instead of hashtable.
	(stream_finalised): No longer required.
	(camel_data_cache_add): objectbagise
	(camel_data_cache_get): "
	(camel_data_cache_remove): "
	(data_cache_path): Set the now expired date before running expiry,
	so it plays better with multiple threads.  Still a couple of
	harmless races.

2002-12-06  Not Zed  <NotZed@Ximian.com>

	* providers/local/camel-spool-store.c (scan_dir): folders ->

	(get_folder_counts): folders -> object bag.

	* camel-vee-store.c (vee_get_folder): changes for folders
	objectbag.

	dont refresh the base folder if we're in FAST mode.
	(build_info): Removed, no longer needed.
	(vee_rename_folder): Fixed for folders objectbag.

	* camel-store.c (camel_store_init): init the folders objectbag.
