another thread to the mainthread in a safe manner.
This is used for the DNS lookup code, and can also
be used by the signal handler to safely report actions back
to the application mainloop without using global variables.
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.
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.
Dynamic commands are user commands that can be added dynamically to
the hub by a plugin.
The example plugin (mod_example.c) adds a !example command that when
invoked send a message to the user who invoked it.
