OF-973: TLS negotiation failures should come in two flavors.

DefaultUserProvider: Rethrow exception instead of silently logging it.

OF-997 Deny framing to avoid clickjacking

The reason is, that when calling the createUser() method, the caller thinks user creation succeeded, even if it might not.
This leads to unexpected behavior.

I've experienced that, when trying to create a user with a name of > 100 length:

OF-1001 Drop Clearspace support

OF-928 Add a copy of the extendedInformation

Upgrading the Ant Contrib & XmlTask libraries

Admin Console: External Component Settings

The page on which a user can manage the settings for External Components should offer
all features that are available now that the new ConnectionManager has been implemented.

OF-995: Parent plugin identification should not be case-sensitive.

Avoid nested EL delimiters

Nothing should be transmitted when STARTTLS negotiation fails, not even
a stream close.

When STARTTLS fails, there are two distinct types of failure. Each type should
be handled in a distinct manner.

Note that this commit applies a fix to the S2S code only. C2S may also need work.

Possibly a copy/paste glitch from an earlier refactoring exercise.

Fix NPE when accessing AuditManager module

Not sure when this got changed, but the module loader uses the interface
class name as a key, not the implementation class name.

Avoid using classes from sealed packages

This fix was applied a while back on an earlier incarnation of this test
class.

OF-993: Replace thread factory boilerplate code.

Ensure that the MUC room subject is set correctly from initial request
and upon subsequent reload.

Assume a client with MUC elements in presence needs to join

OF-992: Re-init on restart

OF-991: Ant build should use property values when available.

Fix XEP-0012 logic.
