When we are dealing with connected sockets shared between a udpsrc and a udpsink
we might receive ICMP connection refused error messages in udpsrc that will
cause it to go into a bursty loop because the poll returns right away without a
message to read.
Instead of looping, read the error message from the error queue in udpsrc.
Fixes#567857.
Link to properties. Correct titles for examples. Document a few trivial cases. Keep lists in section file and docs/plugins/Makefile.am alphabetically ordered. Fix warnings that gtk-doc points out.

* gst/udp/gstmultiudpsink.c: (gst_multiudpsink_render):
Make gst_multiudpsink_render() ignore errors from sendto() instead of
breaking streaming. Emit a warning instead. Fixes#562572.

* gst/udp/gstudpsrc.c: (gst_udpsrc_create), (gst_udpsrc_start):
OS X's bind() implementation is picky about its addrlen parameter and
fails with EINVAL if it is larger than expected for the socket's address
family. Set the length to the expected length instead. Fixes#553191.

Original commit message from CVS:
* gst/udp/gstudpnetutils.c:
EAI_ADDRFAMILY was obsoleted in BSD at some point. Define it to the
old value (1) if it's not defined which should not cause any problems
as we're using it internal only anyway.
Original commit message from CVS:
* gst/udp/gstudpsrc.c: (gst_udpsrc_start):
Call getsockname() after the call to bind() to get updated values
for the port, etc. This fixes the usage of udpsrc on anonymous
binding and it's usage by rtspsrc. Fixes bugs #539372, #539548.
Thanks to Aurelien Grimaud for pointing out the obvious fix.

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.
