OF-1244: Admin console DNS SRV evaluation

OF-1245: Prevent error while parsing self-generated certificate

Openfire, during setup, generates a certificate, that it cannot parse later.

This commit changes the generation routine, changing the subjectAltName value
from a tagged object to non-tagged string.

This commit adds an admin console page that allows an administrator to evaluate
the DNS SRV configuration in context of the XMPP domain name and fully qualified
domain name of the sever that is running Openfire.

OF-477: Improve default XMPP domain name and FQDN

This change means that room subject changes are no longer held within the
history transcript, but instead are always sent in a distinct action afterward.

Although this means that repeated changes will not be replayed in history, this
seems to be normal behaviour on other servers, and simplified the history replay
code considerably.

This commit intends to have better default values for two properties of Openfire:
- the XMPP domain name (eg: igniterealtime.org)
- the FQDN of the server (eg: xmpp.igniterealtime.org)

Older code did not always make a clear distinction (ambiguously referring to
'server name'). Having a proper FQDN has become more important, as newer SASL
implementations depend on the client using the same FQDN as what is configured
in the server).

This commit removes support for changing the XMPP domain name at run time (although
you can obviously still change the corresponding property). Instead, the FQDN can
now be changes (although will require a restart).

Additionally, the XMPPServerInfo implementation got a bit of a refactoring: values
that are not expected to be modified (or considered unmodifiable from a functional
perspective), are no longer passed around, but are rather hardcoded in the
implementation. Support for deprecated ServerPort was removed.

Finally, most access to the properties that hold the XMPP domain name and FQDN
are now encapsulated by XMPPServerInfoImpl.

* javadoc fixes and remove legacy SVN RCS tags

* Better javadoc correction as per review

* 4.1.0 Beta

* Remove extraneous bits

Cut and paste is clearly too advanced for me.

OF-1182 remove Release News, expand Blog

Although the RFC doesn't explicitly appear to say this, the SASL profile for
XMPP has historically used "=" as a null indicator in all cases. This patch
builds on Christian's to ensure this is properly checked and handled in
challenge and client-sent cases.

responds accordingly.

OF-1212 Oracle database issues

OF-1217, this change was created by the install4j GUI to update the config
to the current-release (6.1.3) schema.

Refactoring work done in 4.1 release of Openfire lead to an introduction of a requirement on `JiveSharedSecretSaslServer`

When a user is created due to successful authentication, now calls the full process of user creation, including firing events for plugins. (#689)

OF-1235 Fixes user_created event not being fired on user creation due to auth.
