On POSIX, IP_MULTICAST_LOOP is a setting for the sender socket. On Windows it
is a setting for the receiver socket. As such we will need it on udpsrc too to
allow filtering out our own multicast packets.
Otherwise we constantly create/close event file descriptors,
every single time we call g_socket_condition_timed_wait() or
g_socket_receive_message(), i.e. twice per packet received!
This was not particularly good for performance.
Also only create GCancellable on start-up.
On Windows it's not possible to bind to a multicast address
but the OS will make sure to filter out all packets that
arrive not for the multicast address the socket joined.
On Linux and others it is necessary to bind to a multicast
address to let the OS filter out all packets that are received
on the same port but for different addresses than the multicast
address
And deprecate the multicast-group property and replace it with the
address property.

Add network interface selection when joining multicast groups.
Useful when using the udpsrc on multihomed hosts.
Fixes#575234.

* gst/udp/gstudpsrc.h:
Add property to control automatic join/leave of multicast groups.
Add G_LIKELY.
Remove setting caps on buffers explicitly, basesrc does that for us now.
Improve debug info.
Convert some non-fatal error into warnings.
Use g_ntohs for better portability.
Leave multicast groups when stopping.
When using external sockets, use getsockname() on them to fill up the
addr structure before calling methods that use the structure.
Should all fix#536903.

Original commit message from CVS:
Remove all config.h includes from header files, add it to each source file and remove duplicate config.h includes from several source files
Original commit message from CVS:
(1) Caps nego are now dynamic, the Application developer now have choices: udp, tcp & none.
(2) Broadcast flag set to true on all the udp sockets.
