326292681a Add maximum-qos support to broker and client. 
This comes in the form of:

* Per listener maximum_qos option, which can be in the range 0-2.
* Changes to mosquitto_publish*() to return MOSQ_ERR_QOS_NOT_SUPPORTED
  if attempting to publish with a higher QoS than supported.
* Bridges will downgrade messages to match the maximum QoS.

More tests on the broker side (specifically bridges) are required. This
needs bridge support for MQTT 5 first.

84660e1cbe Send maximum limits for QoS>0. 
This needs more work on the broker front to simplify the design.

e169f1c7c2 When using ADNS, don't ask for all network protocols when connecting. 
This can lead to confusing "Protocol not supported" errors if the
network is down, because UDP sockets are provided.

Thanks to jsaak.

Closes #1062.

c6aac741c2 broker: support byte based queueing 
Limiting queued message depth purely based on message count is hard to
control for memory constrained devices.  The size of messages can vary
wildly, from a few bytes, to a few kilobytes.  Support a new
max_queued_bytes option, and drop packets when the first limit is
reached.  Option defaults to 0 (disabled) by default.
Support also a max_inflight_bytes variable, with similar behaviour.

Fixes (partof) https://github.com/eclipse/mosquitto/issues/100

This pulls up some helper routines for calculating whether to allow
inflight or queuing, resolving some inconsistences in connection
resumption.

af995d211d Fix client library keepalive handling. 
Fix the case where a message received just before the keepalive timer
expired would cause the client to miss the keepalive timer.
