Further fixes in pop3.

* libproto/pop/pop3_create.c (_mu_pop3_init): Fix return value.
* libproto/pop/pop3_destroy.c: Add missing includes.
* libproto/pop/pop3_stream.c (_pop3_decoder): Remove the final
.\r\n altogether.
* mailbox/fltstream.c (filter_read): Remove the hack for supporting
buggy filters.
