Seconds since the Unix epoch is not a parameter that can be obtained
with strftime on Windows.

Closes #1908. Thanks to Danil intl.

Prior to this, duplicate entries could be added to the sock hash, which caused an infinite loop. Only affects bridges with bad settings on startup, and only when compiled using WITH_ADNS=yes.

Closes #1897. Thanks to Rodolfo Ochoa.

Closes #1905. Thanks to Taavi Talvik.

Closes #1880. Thanks to J1EXA, richl, and EnneiteZer.

This occurred when reloading a persistence file and
`per_listener_settings true` is set and the client did not set a

<arpa/inet.h> header is required to compile this source. Without it, WARNING is generated.

In some circumstances, Mosquitto could leak memory when handling PUBLISH  messages. This is limited to incoming QoS 2 messages, and is related to the combination of the broker having persistence enabled, a clean session=false client, which was connected prior to the broker restarting, then has reconnected and has now sent messages at a sufficiently high rate that the incoming queue at the broker has filled up and hence messages are being dropped. This is more likely to have an effect where max_queued_messages is a small value. This has now been fixed.

Closes #1793. Thanks to mbates14.

This fixes the following error, when compiling for systems without
pthread support, and when passing WITH_THREADING=no to make:

    thread_mosq.c:24:12: fatal error: pthread.h: No such file or directory
     #  include <pthread.h>
                 ^~~~~~~~~~~
    compilation terminated.

It was grouped with the callbacks, where it didn't make a lot of sense.

Was listed in both client options, and under the callbacks.
