Bugfixes

* libmailutils/filter/base64.c (_base64_encoder): Fix for the case
when cmd==mu_filter_lastbuf and isize==0.

* libmailutils/stream/tcp.c (mu_tcp_stream_create_with_source_ip)
(mu_tcp_stream_create_with_source_host): Don't treat EAGAIN and
EINPROGRESS as errors.
* libproto/mailer/smtp.c (smtp_open): Free sockaddr if
mu_tcp_stream_create_from_sa failed.
* libproto/pop/mbox.c (pop_open): Likewise.
* mu/imap.c (com_connect): Likewise.
* mu/pop.c (com_connect): Likewise.
