        * camel-simple-data-wrapper.c (construct_from_stream): If we
        already have been constructed, unref our content.
        (write_to_stream): Check we've been constructued, and change for
        stream api changes.

        * camel-mime-parser.c: Removed exception stuff.

        * md5-utils.c (md5_get_digest_from_stream): repaired.

        * camel-mime-message.c: Remove exception from write_to_stream, and
        fix, and fix formatting.

        * providers/sendmail/camel-sendmail-transport.c (_send_internal):
        Fix for stream changes.

        * providers/pop3/camel-pop3-store.c (camel_pop3_command): Fixes
        for stream changes.

        * providers/mbox/camel-mbox-folder.c, and elsewhere, fix all
        stream api changes.
        (mbox_append_message): Use stream_close() now its back.
        (mbox_append_message): unref the from filter.

        * camel-stream-mem.c: And here.

        * camel-stream-fs.[ch]: Here too.

        * camel-stream-filter.c: Likewise.  This is getting tedious.

        * camel-stream-buffer.c (stream_write): Fix a few little problems.
        (stream_close): Reimplmeent.
        (camel_stream_buffer_read_line): Slightly more efficient version,
        that also only allocates the right amount of memory for strings.

        * camel-seekable-substream.c: Likewise.

        * camel-seekable-stream.[ch]: Remove exceptions, fix formatting,
        changes for stream (re)fixes.  set_bounds returns an error.

        * camel-stream.[ch]: Remove exceptions.  Make flush and reset return
        an error code, repair all the screwed up formatting, and put back
        close.

        * camel-mime-part-utils.c
        (camel_mime_part_construct_content_from_parser): And here.

        * camel-mime-part.c (camel_mime_part_set_content): And this too.
        (write_to_stream): Fixed for stream changes.

        * camel.h: Fixed.

        * providers/vee/camel-vee-folder.c (vee_search_by_expression):
        Implement.  Performs an intersection of the two searches.
        (camel_vee_folder_finalise): Unref search folders.
        (vee_append_message): Implement append.
