Francesco Nigro b5fa5ed3b7 ARTEMIS-1656 OpenWire scalability improvements
OpenWireFormat instances are shared between OpenWire connections/sessions/consumers, preventing the clients to scale due to the synchronized marshal/unmarshal on it.

It includes:
- direct transport buffer pooling
- groupId SimpleString pooling
- clientId SimpleString pooling
- reduced ActiveMQDestination[] and AtomicLong allocations on AMQSession:send
- reduced ActiveMQDestination allocations
- refactored shouldBlockProducer path of AMQPSession::send to reduce method size
- exclusive OpenWireFormat per session and connection (in/out) to avoid contention
- refactored trace log to favour inlining
- changed lastSent volatile set into lazy set to avoid full barrier cost on x86
- stateless OpenWireMessageConverter
- send's lock removal thanks to thread-safe NettyConnection
