Log message:
        In order to boost performance, when doing the scan we use
        the approach of downloading part of the header of the total
        set of messages.  The it was done before is that the headers
        were ask one by one per message.  This was causing performance
        delay because we were doing a lot of small transaction on
        the TCP/IP stack.  By bundling the entire thing in one request
        there was much less transcation and the speed was increase
        by a factor of 10++.
        The Imap code folder_imap.c and mbx_imap.c is now messy.
        The rewrite in mailbox2 should clean this up though.
        
        * mailbox/folder_imap.c (imap_quoted_string): Allocated the
        memory instead.
        (imap_body): If we were doing the scan free the memory and create
        the cache header.
        (imap_fetch): Create the message if was not done, important for
        the scan.
        * mailbox/mbx_imap.c (imap_scan): Bundle one big request to
        fetch as much information as possible.
        (message_operation): Free the buffer when done.
        * mailbox/include/imap0.h: Add IMAP_SCAN states.
        
        * mailbox/file_stream.c (_file_readline): It seems that fgets() can
        not handle binary data.  Try to do our best.
