Openfire 3.10.0 GA Release!

Mutual authentication support depends on certificates being available in the client
truststore. Openfire does not ship with any by default, and does not provide any tools
to manage certificates in any of the truststores. This commit adds basic support, which
allows a user to add, remove and review certificates in any of the keystores that are
available in Openfire.

Change OF-888 fix to be based on error

OF-888 is presumed to be a recursion due to an attempt to bounce a bounce, in
other words it's failing to handle a double-bounce.

It appears to be caused when routing a stanza from a MUC fails, and for some
reason I don't yet understand, the routing of the bounce to the originating
MUC source also fails.

The test for the double bounce is only present for the IQ case, but this fails
in any case because it tests only for the IQ case, and uses a test which checks
the IQ's symbolic type; this is not actually set by Packet.setError(), so does
not trigger.

Tom's fix inserted a sentinel into the original failing stanza, however a new
stanza is created for the bounce, which will not contain the sentinel; therefore
the fix will not protect from a recursion.

Therefore this patch:

1) Removes Tom's fix for OF-888.

2) Tests for the message and presence error types.

3) Tests for the presence of a stanza error (though this is a warning).

4) Explicitly sets the stanza error type.
