new abstract class for disconnectable remote stores
* camel-disco-store.c: new abstract class for disconnectable remote stores * camel-disco-folder.c: new abstract class for folders on disconnectable stores. * Makefile.am: Add camel-disco-folder.[ch] and camel-disco-store.[ch]. * providers/imap/camel-imap-store.c: Make this a subclass of CamelDiscoStore, and fix up the offline interfaces for the changes since they were first written (particularly the fact that some IMAP stores don't just use subscribed folders). * providers/imap/camel-imap-folder.c: Make this a subclass of CamelDiscoFolder, although most ops still fail in disconnected mode. * camel-store.c (camel_store_get_folder_info): Change gboolean, gboolean, gboolean to guint32 in the prototype for this function. * providers/local/camel-local-store.c (get_folder_info): Update for prototype change. svn path=/trunk/; revision=9659
