Denote Openfire 4.1.1 Release

Exception handling is used to determine if the default admin console username/password
applies. This exception handling should be more specific than depend on any Exception.
Instead, authentication-related exceptions should be used.

This fix applies to the Client Control plugin.

* OF-1254: Correct database version in update script 25.

Most database update scripts version 25 identify themselfs incorrectly as 24. This causes the update script to be executed each time that Openfire starts.

* OF-1255: Fix Mysql installation script.

This removes an offending semicolon.

Denote Openfire 4.1.0 Release

Move the logged exception when `null` keys are allowed for storage to debug leve.

OF-1246 MAM for MUC

OF-867 Wrong key in groupMetaCache evict

OF-512: Allow 'reported' streamhost to be modified.

The file transfer proxy will listen on, and report, a set of network interfaces. Sometimes, the proxy
is not reachable on these addresses directly (for instance in a network environment where NAT comes
into play).

This commit re-purposes the 'xmpp.proxy.externalip' property. Earlier, this was used to make the proxy
bind to a specific interface. As this is quite similar to the functionality provided by the
'network.interface' property, 'xmpp.proxy.externalip' now controls only what interface is reported. It
no longer affect the interface binding process directly. This functionality has also been added to the
admin console.

OF-1156 Warn (and possibly die) on null storage in DefaultCache

Hazelcast clustered cache implemented by MapProxyImpl by preventing null
keys and values being added. Also document this behaviour in the Cache
interface.

OF-477 correct tooltip message in setup

In one case, the outgoing stream header includes the wrong domain, which causes an error in SASL EXTERNAL on some servers.

Note that this also fixes numerous bugs with general MAM itself. A full
comparitive test run was not performed, so it is unclear how many issues
were present in previous builds.

The "with" field is mandatory within MAM, but is not within MAM-MUC; it is
therefore ignored. The specification remains unclear on whether this is
legitimate.

This patch updates the database for MAM-MUC support:
* Upgrade scripts simply update the version, since previous patches included these updates in upgrades.
* New installations have the fields added.
* MUC history logging adds the MAM message identifier.

untested by me, patch by @aberenguel

OF-1228 Prevent NPE on first boot

OF-1247 HSQL VARBINARY now requires length

related to upgrade of HSQL done with OF-955 PR#679

* OF-1188 Add remote domain access check in main thread

By adding an additional access check fo the remote domain in the main loop,
we avoid the need to tie up an OutgoignSessionPromise thread during S2S
initiation.

* OF-1188 Improve logging

Note that audit-policy *is* covered, though appears not to be.

Several of these will re-present the form without processing now.
