/* This is the main driving function of this module.  It generates a
   document of type message/rfc822, which contains the stuff provided.
   The first few arguments are the standard header fields that the
   generated document should have.

   `other_random_headers' is a string of additional headers that should
   be inserted beyond the standard ones.  If provided, it is just tacked
   on to the end of the header block, so it should have newlines at the
   end of each line, shouldn't have blank lines, multi-line headers
   should be properly continued, etc.

   `digest_p' says that most of the documents we are attaching are
   themselves messages, and so we should generate a multipart/digest
   container instead of multipart/mixed.  (It's a minor difference.)

   The full text of the first attachment is provided via `attachment1_type'
   and `attachment1_body'. These may all be 0 if all attachments are
   provided externally.

   Subsequent attachments are provided as URLs to load, described in the
   nsMsgAttachmentData structures.

   If `dont_deliver_p' is false, then we actually deliver the message to the
   SMTP and/or NNTP server, and the message_delivery_done_callback will be
   invoked with the status.

   If `dont_deliver_p' is true, then we just generate the message, we don't
   actually deliver it, and the message_delivery_done_callback will be called
   with the name of the generated file.  The callback is responsible for both
   freeing the file name string, and deleting the file when it is done with
   it.  If an error occurred, then `status' will be negative and
   `error_message' may be an error message to display.  If status is non-
   negative, then `error_message' contains the file name (this is kind of
   a kludge...)
