Workaround for mail loop for sympa-request address (#1018)

Additional fix to #973 & #997 (#969)

sympa_newaliases.pl: Removing ineffective command line options

As of Postfix 2.3, Content of Return-Path: pseudo-header field added by pipe(8) for null envelope sender became "MAILER-DAEMON".  Empty `null_sender` option will prevent this behavior.
As a workaround, the uppercase "<MAILER-DAEMON>" will be treated as null envelope sender.

Mail loop with sympa-request address because of misconfiguration (#957)

Updating Sympa::List's POD

sympa.pl: Add an option "--rebuildarc=list@domain" to rebuild archives

<sympa-request> address should not be forwarded to any functions of Sympa.  To avoid mail loop by such misconfiguration, discard messages bound for this address.

Additional fixes to: Racke/no save method in sympa list module

ARC::Signer died because of a malformed "Authentication-Results:" header field (#988)

Additional fix to #973 (#969)

There is no save method in Sympa::List anymore.

Relative to #993: with this option, we can rebuild all archives with a
simple `for` bash loop, without restarting from beginning if
`archived.pl` restarts while rebuilding all lists.
