00952be424 udp: Enable address reuse by default for multicast 
Keep the original corner case behaviour, where reuse is enabled
for the case where no argument is given to the reuse url option.

a8475bbdb6 os: replace select with poll 
Select has limitations on the fd values it could accept and silently
breaks when it is reached.

c6610a216e Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice. 
This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.

21a569f302 udp: Allow specifying the connect option in udp_set_remote_url, too 
If the remote address is updated later with this function, the caller
shouldn't set the connect option until in this call.

6766a354f7 udp: Add an option for connecting the udp socket 
This allows us to find out the local sending address via getsockname,
otherwise we just get INADDR_ANY (or similar for v6).

This also makes writes return ECONNREFUSED if nobody is listening on the
receiving port.

55b6bd1c01 Convert ff_is_multicast_address to take a struct sockaddr parameter 
Not all users of this function will have a full struct sockaddr_storage
available, and casting other sockaddrs to sockaddr_storage is wrong,
while any sockaddr can be cast to a base sockaddr.

7ac57fa5eb Share the is_multicast_address function 
The header probably isn't the right permanent place for this function, but
it is quite small, and consensus seems to be that it can stay in the
header for now, instead of creating a new file network.c just for this one.

f0a8039464 Add url_get_file_handle(), which is used to get the file descriptor 
associated with the I/O handle (e.g. the fd returned by open()). See
"[RFC] rtsp.c EOF support" thread.

There were previously some URI-specific implementations of the same idea,
e.g. rtp_get_file_handles() and udp_get_file_handle(). All of these are
deprecated by this patch and will be removed at the next major API bump.
