This happened due to the network polling mechanism had nothing to poll
for, so it returned immediately only to be called again (during DNS lookup).
This fix introduces a control pipe that is polled for reading, althoug nothing
is ever sent to that pipe. But, it can be used instead of the signal
handler approach which is currently used for terminating the program.
the given amount of messages in the configured interval.
The previous behavior allowed n+2 messages in the interval, due to
two off by one comparison rules.
In addition, if flooding is detected then each new message after the flooding
is detected will reset the interval timer, which means the client
cannot send another message until the timeout interval expires.
This could essentially happen due to time drift,
high load, or the process being put in sleep for a while.
The reason is that recurring timers could be added to the same time slot
as the timeslot being handled.
Use file=/path/to/db to specify the database file where chat history should be stored. Other config variables are the same as those for mod_chat_history.

This used to be a linear search O(n), but is now done
as a red-black tree O(log n) instead.
These operations can be further opimized with a hash-table
which would acheive near constant time lookups.
- Added a list_remove_first() which is generally better than list_remove()
provided you want to remove the first element.
- Added a list_append_list() to append and move all nodes from one list to
another.
Previously you would have to do something like this:
for (type foo = (type) list_get_first(list); foo; foo = (type) list_get_next(list)
{
/* code */
}
Now, you can instead write this as:
LIST_FOREACH(type, foo, list,
{
/* code */
})
Basically, boilerplate stuff including the casting is gone.
This API provides transparent asynchronous DNS lookups
with both IPv4 and IPv6 support, and in addition will try
to connect to all addresses until one of them work.
This implements the "happy eyeballs" algorithm provided that the client supports IPv6
and that the DNS records provides both IPv6 and IPv4 addresses.
This caused the backends to return an error code, which
in turn ended the mainloop. However, several other things
also might occur in the main loop, such as DNS lookups which
come prior to creating any connections that in turn would be monitored.
