98b76bb11f avformat/rtsp: add support for satip:// 
The SAT>IP protocol[1] is similar to RTSP. However SAT>IP servers
are assumed to speak only MP2T, so DESCRIBE is not used in the same
way. When no streams are active, DESCRIBE will return 404 according
to the spec (see section 3.5.7). When streams are active, DESCRIBE
will return a list of all current streams along with information
about their signal strengths.

Previously, attemping to use ffmpeg with a rtsp:// url that points
to a SAT>IP server would work with some devices, but fail due to 404
response on others. Further, if the SAT>IP server was already
streaming, ffmpeg would incorrectly consume the DESCRIBE SDP response
and join an existing tuner instead of requesting a new session with
the URL provided by the user. These issues have been noted by many
users across the internet[2][3][4].

This commit adds proper spec-compliant support for SAT>IP, including:

- support for the satip:// psuedo-protocol[5]
- avoiding the use of DESCRIBE
- parsing and consuming the com.ses.streamID response header
- using "Transport: RTP/AVP;unicast" because the optional "/UDP"
  suffix confuses some servers

This patch has been validated against multiple SAT>IP vendor devices:

f3891430fc avformat/rtspdec: fix potential mem leak in listen mode 
Currently a repeating setup request (with the same stream id) will
simply overwrite rtp_handle/transport_priv without freeing the
resources first. This is fixed by closing the previous setup request.

423d06e0e2 avformat/rtspdec: add network init to listen mode 
As per the docs network initialization is required before ff_url_join().
Furthermore, because the ff_network_init() was skipped, this makes
one additional call to ff_network_close() if the stream exits without
errors.

fab8156b2f avio: Copy URLContext generic options into child URLContexts 
Since all URLContexts have the same AVOptions, such AVOptions
will be applied on the outermost context only and removed from the
dict, while they probably make sense on all contexts.

This makes sure that rw_timeout gets propagated to the innermost
URLContext (to make sure it gets passed to the tcp protocol, when
opening a http connection for instance).

Alternatively, such matching options would be kept in the dict
and only removed after the ffurl_connect call.

cdcc370293 rtsp: punch holes again after pause 
When a client behind a NAT issues a pause command, and stay paused for a
long time, the router may stop the RTP/RTCP port redirection. Resend the
hole punching packets before each PLAY command to cause the router to
restart the port redirection in that case.

Move the existing code for sending the packets from the SETUP phase
to the PLAY phase.
