Incidentally also remove a warning.

Some code paths can call it with invalid length.

'filter' is too generic, since the functions in question deal with
several filters.

Also add const qualifiers to those variables.

This function should never modify the filter.

The actual usage of the pragma is within functions and older versions
of gcc only support the pragma outside of functions.

Set output_picture_number in H.264 parser.

A separate rtcp port can already be set when opening the rtp
protocol normally, but when doing port setup as in RTSP (where
we first need to open the local ports and pass them to the peer,
and only then receive the remote peer port numbers), we didn't
check the same url parameter as in the normal open routine.

I doubt that anyone ever would try to send a 1 byte packet
via the RTP protocol, but check just in case - it shouldn't
crash at least.

AVIOContext has got an av_class member that only gets set if
opening the context using avio_open2, but not if allocating a
custom IO context. A caller that wants to read AVOptions from
an AVIOContext (recursively using AV_OPT_SEARCH_CHILDREN) may
not know if the AVIOContext actually has got a class set or not.

Mixing these with the rtp depacketizer functions in rtpdec.h is
no good.

This avoids having duplicate code where only the fd parameter
differs.

The fdset is a pollfd array nowadays, and it is already populated
at this point.

With the most annoying memory leak found by Derek Buitenhuis.

This allows the chained demuxer (or more precisely, the lavf
utility code) to better fill in timestamps on packets from
these, especially for cases where one stream is a raw ADTS
stream.

Add support for domain names, for multiple source addresses,
for exclusions, and for session level specification of addresses.

This allows us to explicitly fail if the caller tried to set
both inclusions and exclusions at the same time.

Previously this only allowed literal IP addresses. When these
are conveyed in a SDP file as in RFC4570, host names are allowed
as well.

Also fix some similar typos in comments and documentation.
