This patch is to prevent a stack overflow in certain exception cases
where a connection has been closed, but its corresponding session is
still present in the routing table.

and remove null checks.

Related to OF-855.

This patch fixes several NullPointerExceptions that were observed in an
cluster when running under high load and latency, including related
issues in the BOSH connector and hazelcast plugin. Some related logging
improvements are also included.

Some of the NPEs were generated during the startup phase before the
server was fully initialized. These have been corrected by checking
appropriate "ready state" indicators.

In general, sessions hosted in remote cluster nodes that cannot be
addressed due to timeouts during remote task execution should be
considered temporarily "unavailable" to the cluster member that
initiated the call.

Check the underlying connection for a given session before delivering a
packet; if the connection is missing, clean up session and resend packet

Use a lock to ensure the integrity of IoSession (MINA), especially when
using compression or TLS filters

OF-859: Pubsub fix; misc cleanup

This fixes a problem with a static final reference in the Node.class. It
also addresses a couple of minor issues discovered during pubsub
testing:
- PubSubPersistenceManager should return an editable collection rather
than a read-only collection for published items
- SequenceManager defaults should use a blocksize of 5 for frequently
used tables
- LocaleUtils should catch and log a MissingResourceException and return
the key in lieu of the missing value (by convention)

OF-857: Fix C2S locking issues

Updates the MINA 2.0.9 core to fix a locking issue documented here:
https://issues.apache.org/jira/browse/DIRMINA-995

Also updates connection manager and thread pool configurations to better
allocate resources within the JVM.
