Subject: implement the new counts, and get them all atomically so they're only

2004-04-13  Not Zed  <NotZed@Ximian.com>

        * camel-folder.c (folder_getv): implement the new counts, and get
        them all atomically so they're only calculated once and can return
        consistent results.

        * camel-folder.h: Added CAMEL_FOLDER_DELETED, CAMEL_FOLDER_JUNKED,
        and CAMEL_FOLDER_VISIBLE args, to support client display of
        various values.
