Fix handling of stdin stream (in particular, in sieve).

* libsieve/extensions/spamd.c (spamd_test): Fix typo.
*  mailbox/file_stream.c (struct _file_stream): New members
size and size_computed.
(_stdin_file_read, _stdin_file_readline): Fix types of fs_offset.
(_stdin_file_size): New function.
(_stdout_file_write): Register _stdin_file_size as stream_size
method if seekable flag is set.
* mailbox/message_stream.c (struct _mu_rfc822_message): Remove
unused member.
* sieve/sieve.c (sieve_message): Create a seekable stream.
