Add messageinfo to id table, and store array index in messageinfo too.
2002-08-06 Not Zed <NotZed@Ximian.com> * providers/pop3/camel-pop3-folder.c (cmd_list): Add messageinfo to id table, and store array index in messageinfo too. (fi_to_index): Removed, use index member of messageinfo, fixed callers. (cmd_builduid): Parse the headers of the data, and ignore any status or x-status headers. (uid_to_fi): Removed, use the hashtable instead. (id_to_fi): Same. (cmd_uidl): Add messageinfo to uid table. (pop3_refresh_info): Setup hash tables, and fill out uid table for nonuid capable servers. (pop3_finalize): Destroy hash tables. Only free resources if the uids table is not null (if finalised before we ran refresh info). (id_to_fi): Removed. Use id hash table instead, fixed caller. svn path=/trunk/; revision=17706
