Fix #31 — Fix order of list’s config params

Additional fix to #593

Add sympa.conf-dist

Fixed by opening aliases file as Sympa::LockedFile instance.
Note: To keep exclusive processing by file lock effective, file won't be closed (unlocked) before newaliases will be finised.

Sympa::Aliases::Template creates exclusive lock on local storage

Additional changes to: Salaun urennes1/fix scenario name with dots (#589)

Sympa::Scenario::new() was unable to load scenario filename including dots

PR#582 addition 1

Fix tt2 indentation

Note: Message catalog should be tweaked.

dkim_sign: Normalize CRLF->LF for DKIM-Signature

ARC: Comment in Authentication-Results field prevents check on srvid (See #575)

See https://rt.cpan.org/Public/Bug/Display.html?id=129066

- `sympa.conf-dist` always contains all available configuration settings,
  letting admins copy those they want in `sympa.conf`;
- it’s generated at `make`, getting the settings from `Sympa::ConfDef` module;
- it’s installed in `$sysconfdir` at `make install`.

This behavior is useless when aliases file is shared by multiple hosts with network drive.
Fixed by creating lock at the same place as aliases file.

Slight change in list admins cache expiry.

Sympa::Scenario::new() was unable to load scenario filename including dots. Example: visibility.igr.univ-rennes1.fr

Fix #548 — Add DB log entry when message is rejected or distributed via email

Mail::DKIM::Signer wraps DKIM-Signature with with \r\n\t; this
is the hardcoded Separator passed to Mail::DKIM::TextWrap via
Mail::DKIM::KeyValueList. MIME::Tools on the other hand
(MIME::Head::stringify() in particular) encode EOL as plain \n;
it is thus necessary to normalize CRLF->LF for DKIM-Signature to
avoid confusing the mail agent.

Fixed by parsing the field according to standards.

When changing a list's admin two times in the same second, the list admins cache is not updated. Consequently, when trying to add a third admin in the same second, the second one is not in the cache at the time.
Obviously it does not sound like a recurrent scenario and I met this problem when running a test file only.
However, it is possible that this happens more often when trying to make batch modifications in the shell. And also, it made my test fail which is an engineering problem: it could be misguiding about the cause of a test failure.
So I changed the expiration test, replacing "<" by "<=" and it solves the problem.
I don't see any side problem that could result from this change bu I commit it separately anyway because the cache is very sensitive.

Upgrade: A typo breaks configuration (#578)

WWSympa: TLS client authentication: Get email from certificate according to S/MIME

- 4 spaces indentation
- Indent on HTML tags AND on TT2 stuff ([% IF … %])
- Avoid HTML or TT2 oneliners like:
```
  [% IF top_menu %]…[% END %]
  <div class="displayNone"><a href="#top">Top of Page</a></div>
```
- When a tag has too many attributes to be on one line, indent the
  attributes at the same level than the first one:
```
<label class="foo"
       id="bar">
    Baz
</label>
```

WWSympa: TLS client authentication: Now it gets rfc822Name in X.509v3 subjectAltName, otherwise emailAddress attribute in subject DN (the first one of either).

Note: Earlier efforts getting attribute such as MAIL, Email in subject DN are no longer supported.
