This means we can use some newer features and get rid of some
boilerplate code using the G_DECLARE_* macros.
As discussed on IRC, 2.44 is old enough by now to start depending on it.
Otherwise we constantly create/close event file descriptors,
every time we call g_socket_condition_timed_wait() or
g_socket_send_message(s)(), i.e. a lot. Which is not
particularly good for performance.
Can't create GCancellable in ::start() here because it's used
in client_new() which may be called via the add-client action
signal which may be called before the element is up and running.
We unlock and re-lock the client lock while emitting the
removed signal, which causes inconsistencies in the client
list vs. the client counts. Instead, remove the client from
the list already before emitting the signal and put it into
a temporary list of clients to be removed. That way things
look consistent to the streaming thread, but signal callbacks
can still do things like get stats from removed clients.
Add prototype for a render_list() function that can use a
sendmmsg-style g_socket_send_messages() function once it lands
in GLib. We can use this infrastructure to send multiple buffers
made up by multiple memories to multiple clients in one go, which
drastically reduces the number of syscalls made when sending
high-bitrate video streams.

Use the refcount for memory management and keep track
of the number of duplicate clients in a separate
variable. This will be useful later, and means we
don't have to hold the OBJECT_LOCK all the time.

udpsrc already has support for setting the multicast interface, which
is useful for multi-homed machines. This patch adds the same code to
the multiudpsink.
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=685864
Add an option to the multiudpsink that makes it possible to force
the use of an IPv4 socket.
This can e.g. be used to handle the issue described in
https://bugzilla.gnome.org/show_bug.cgi?id=682481
Instead of adding multiple client structures for the same host/port pair, use a
refcount.
Add a send-duplicates feature that allows you to disable sending multiple copies
of the same packet to the same host when it was added multiple times. The
send-duplicates property is by default set to TRUE for backwards compatibility
although it is very likely that this is not desired behaviour.
