New file. Protoypes for the Mail Folder Cache, which provides a place for

2001-07-02  Peter Williams  <peterw@ximian.com>

        * mail-folder-cache.h: New file. Protoypes for the Mail Folder Cache, which
        provides a place for all the disparate pieces of the mailer to save bits of
        information about a folder. Centralizes the information display code.

        * mail-folder-cache.c: New file. Implements the Mail Folder Cache.

        * Makefile.am (evolution_mail_SOURCES): Add the mail-folder-cache.{c,h}

        * folder-browser-factory.c (fb_get_svi): Copy of that absurdly long-named
        function in mail-display.c that gets the GNOME_Evolution_ShellView.
        (control_activate): Set the ShellView for the folder cache.

        * folder-browser.c (got_folder): Tell the folder browser about this folder.

        * mail-callbacks.c (create_folders): Tell the folder cache about the new
        folders.

        * mail-local.c (reconfigure_folder_reconfigure): Don't unhook our
        events as we no longer hook them up.
        (register_folder_registered): Tell the folder cache about this
        folder's place in the local storage.
        (register_folder_register): No longer hook events; the Folder Cache
        will do this.
        (local_folder_changed, local_folder_changed_proxy): Move to mail-folder-cache.c
        (free_local_folder): No longer unhook events.

        * mail-ops.c (do_update_subfolders_rec): Instead of setting the
        folder status ourselves, inform the Folder Cache about the changes.

        * mail-tools.c (mail_tool_uri_to_folder): Replace danw's cache
        with the new Mail Folder Cache.
        (cache_folder, etc): removed.
