This PR removes the use of common buffer used for creating and transmitting packets. The reception will be handled in the user provided buffer.

addWillAndConnectInfo is only called from sendConnectWithoutCopy. Can we incorporate addWillAndConnectInfo into that function instead?

Doing that increases the complexity score.

I'm not sure that this improves clarity really. Wouldn't it be simpler just to fill the array?

Does sendSubscribeWithoutCopy need to be a separate function?

* CBMC: Add memmove stub to accelerate coverage

The commit adds a stub for memmove accelerate CBMC coverage
calculation.  Without this stub, coverage for `MQTT_ProcessLoop` and
`MQTT_ReceiveLoop` fails to converge (gets stuck generating the SAT
formula for the memmove in `receiveSingleIteration`).  This stub
checks that src and dst are nonnull pointers and havocs dst.

* Fix formatting
