Commit f9a28c03 f9a28c0373000d37b6021eaf845fec23f7608eb8 by Sergey Poznyakoff
Options

Improve generation of session identifiers for server programs 

* include/mailutils/acl.h (mu_acl_set_session_id): Remove proto.
* include/mailutils/server.h (mu_session_id): Remove extern.
(mu_sid): New proto.
* libmailutils/server/sid.c: New file.
* libmailutils/server/Makefile.am: Add sid.c
* libmailutils/server/ipsrv.c (mu_ip_tcp_accept)
(mu_ip_udp_accept): Remove calls to mu_acl_set_session_id.
(mu_ip_server_accept): Make sure output to mu_strerr is filtered so
that session ID is prepended to each line.
(mu_ip_server_loop): Remove.
* libmailutils/server/msrv.c (mu_m_server_check_acl): Remove call
to mu_acl_set_session_id.
* libmailutils/server/server.c (mu_session_id): Remove variable.

* imap4d/imap4d.c (get_client_address, set_strerr_flt)
(clr_strerr_flt): Remove unused functions.
(imap4d_connection): Simplify.
* pop3d/pop3d.c: Likewise.
