b816d46508 Use db as a global var instead of passing to functions. 
This allows a big swath of ifdefs to be removed. It also means savings as the db var is not passed around all of the time, and makes it easier to remove the final broker call to mosquitto_time() call in packet_mosq.c. In one test this reduced the calls to mosquitto_time() from 295k to 48k.

c1b009e4df Fix memory leak on handling QoS 2 PUBLISH. 
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.

b91e78318d Don't always iterate over entire inflight messages list 
If we have e.g. max_inflight_messages set to 1000, and currently have 999 messages inflight, then when we send a new message to a client we have to iterate over the whole list to get to the newest message. This change means that we start of the back of the list to find the newest items, which reduces overhead.

Rename mosquitto_plugin_publish() to mosquitto_broker_publish().

These two functions achieve the same thing. *_publish() publishes the payload and frees it later. *_publish_copy() takes a copy of the payload, so the plugin still owns the memory it passed to the function.

1608151569 Fix bridge reconnect 
In the mux_epoll__add_in function, no context->events was set. Previously this was set to match the ev.events (EPOLLIN). Adding this back in, keeps the code consistent to before it was refactored to split out epoll and poll functions, as well as being consistent with the other mux_epoll__ functions.

If this is not set, the connection is never fully established when the broker comes back up.

Fixes #1680.

5481575f8b Fix FormatMessage warnings for Windows. 
From the FormatMessage() Win32 API documentation: "The lpBuffer
parameter is a pointer to an LPTSTR; you must cast the pointer
to an LPTSTR (for example, (LPTSTR)&lpBuffer)."

https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-formatmessage#parameters

This commit fixes warnings like these:
warning C4047: 'function': 'LPSTR' differs in levels of indirection from 'char **'
warning C4024: 'FormatMessageA': different types for formal and actual parameter 5

20972a2819 Add broker ready message. 
Before this commit there was no good way to detect that the
Mosquitto broker was done with its startup phase on systems
without systemd.

On such systems it was tricky to e.g. start the broker from
a test where ports are dynamically assigned and one have to
deal with potential port conflicts.  Without a way to know
that the broker is done with its startup phase, there was no
way to know if the broker was able to acquire the port (for
both IPv4 and IPv6) without waiting for some unknown period
of time (when many tests are run in parallel a single process
might be starved for resources).

With this new broker ready message it is easy for the parent
process to monitor the broker output and figure out when the
port was successfully acquired.

07d73c7e3a bridge: support bridge local clean session 
This adds the ability to separating bridge clean session settings between
the local and remote endpoints.  Some broker implmentations refuse to allow
non-clean sessions, as they don't support storing messages to be sent to
the connecting broker.  However, this doesn't mean that the local
broker can't be queueing messages to send _out_ to the remote broker.

This PR adds a new bridge connection setting, local_cleansession, that
allows controlling this split. Naming is chosen to be local_ in keeping
with the other local_ settings for bridges.

A test for the six cases of queued/not queued messages in both
directions is added, but v5 testing is currently disabled.  The changes
to support the split are ~independent of protocol version.
