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.

In 1.3, 1.4 and 1.5, the function was "libwebsockets_get_protocol" not
"libwebsocket_get_protocol" While the #define name doesn't matter on
newer libwebsockets, where it redirects to lws_get_protocol, the naming
is critical for older versions.

This publishes initial 0 figures for all load averages, as is done for
all the existing counter values in the SYS tree. This makes the
behaviour of certain variables use for diagnostics (stored count for
instance) more predictable, instead of changing due to the creation of
load topics as soon as the load became non-zero.

Instead of simply tracking the count of stored messages, keep track of
the total byte size of stored messages. While only informational at
this point, it provides the basis for byte based limits in the future.

Mosquitto database writes are not atomic and if power is lost during
a write the file will be permanently lost. This commit makes writes as
atomic as possible.

Bug: https://github.com/eclipse/mosquitto/issues/189
The context associated with websocket client didn't had listener
filled, which caused use_username_as_clientid to be ignored.

A lot of function renaming was done in 663d50a016,
and this websockets patch was merged afterwards. Autobuild testing
doesn't have websockets enabled, and missed this.

The WITH_* flags are not handed over to the C++ wrapper, instead it relies on
the actual library to check status.
