Bugfixes.

* libmailutils/streamcpy.c (mu_stream_copy): Use the number of bytes
actually read.
* libmailutils/base64.c (_base64_encoder): Return mu_filter_again
if not all data has been consumed on mu_filter_lastbuf.
* libmailutils/message_stream.c (scan_stream): Fix calculation of
body_end.
(_body_obj_size): Fix calculation of body size.
* libproto/mailer/smtp_data.c (_mu_smtp_data_begin): Set full buffering
on the MU_TRANSPORT_OUTPUT stream.
