Useful in case only the lib is needed.

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.

Fixes eclipse/mosquitto#1904

If the broker rejects the connection, as opposed to the broker being
down, then there is no hope to establish a connection.  This adds a
status flag so we can signal to the loop that we should just exit.

Fixes eclipse/mosquitto#1899

In stdin line mode, mosquitto_pub will continue running and accepting
input even if/when/after publishing fails.  This condition is reached
when it first successfully establishes a connection and the server later
is unreachable.

Exiting with a non-zero exit code allows for much easier health
monitoring when used in a long-running pipe.
