This supports inclusion of one single IP address for now,
at the media level. Specifying the filter at the session level
(instead of at the media level), multiple source addresses,
exclusion, or using FQDNs instead of plain IP addresses is not
supported (yet at least).

If another peer is sending unicast packets to the same port that
we are listening on, those packets can end up being received despite
using source specific multicast. For those cases, manually check the
source address of received packets against the intended source address.

This only handles the case when the source list is one single IP
address for now, which probably is the most common case.

Based on a patch by Ed Torbett.

Blocking/exclusion is not supported yet.

The rtp protocol parameter takes the same form as the existing
sources parameter for the udp protocol.

Also fix a comment and an #endif comment.

There is no record of this ever being used at all, anywhere,
since the feature was added in 2effd274.

This gets rid of extra linker tricks just to support a feature
that isn't used, simplifying portability to other platforms.

If either of the deltas is too large for the multiplications to
succeed, don't use this for setting the avg frame rate.

The time scale is set in mdhd, and later validated in the
enclosing trak atom once all of its children have been parsed.

A loose mdhd atom outside of a trak atom could update the time
scale of the last stream without any validation.

This was handled properly in the normal return case at the end
of the function, but not in this special case.

Returning a value larger than the input packet size can cause
problems for certain library users.

Returning the actual input buffer size unconditionally, since
it is not guaranteed that frame_size is set to a sensible
value at this point.

A frame marked FRAMETYPE_NULL cannot be scalable and requires a
