QPID-3527: update handling of auto-ack messages for 0-10 to send acks (asynchronously) on a per-message basis rather than batching for 1 second, update handling for other ack modes to be clearer with respect to 0-8/0-10 behavioural differences. Remove some redundant methods from AMQSession, updating handling of 'no consume'/'isBrowseOnly' such that BasicMessageConsumer is always supplied a single consistent answer for whether it is non-consuming or not.
Applied patch from Oleksandr Rudyy<orudyy@gmail.com> and myself.
