    pool InVMConnection buffers and copy to retain

    We are running performance tests against Wildfly 10.1.0. Our current tests generate 2400
MB/s of garbage and over 200 MB/s is coming from the InVMConnection buffer allocation. Changing
to Pooled Netty buffers and copying the content into Unpooled buffers when the buffer is retained
(e.g. by  MessageImpl) decreases the allocation rate by 200 MB/s and decreases total GC Pause
time from 39 seconds to 29 seconds.
