In sdp_read_header() some ff_network_close() calls were missed.
Also in rtp_read_header() update comment to explain why a single
call to ff_network_close() is enough to cover all cases even if
sdp_read_header() returns an error.

move comments for the size of SDP_MAX_SIZE here:
Some SDP lines, particularly for Realmedia or ASF RTSP streams,
contain long SDP lines containing complete ASF Headers (several
kB) or arrays of MDPR (RM stream descriptor) headers plus
"rulebooks" describing their properties. Therefore, the SDP line
buffer is large.
The Vorbis FMTP line can be up to 16KB - see xiph_parse_sdp_line
in rtpdec_xiph.c.

1. Remove the assumption that the message method is TEARDOWN.
2. Don't ignore the error code of ff_rtsp_parse_streaming_commands.
Signed-off-by: Martin Storsjö <martin@martin.st>
In listen mode with UDP transport, once the sender has sent
the TEARDOWN and closed the connection, poll will indicate that
one can read from the connection (indicating that the socket has
reached EOF and should be closed by the receiver as well). In this
case, parse_rtsp_message won't try to parse the command (because
it's no longer in state STREAMING), but previously just returned
zero.
Prior to f6161fccf8, this caused
udp_read_packet to return zero, which is treated as EOF by
read_packet. But after that commit, udp_read_packet would continue
if parse_rtsp_message didn't return an explicit error code.
To keep the original behaviour from before that commit, more
explicitly return an error in parse_rtsp_message when in the wrong
state.

It avoids leaving dangling pointers behind in memory.
Also remove redundant checks for whether the URLContext to be closed is
already NULL.

In this example, the difference in length between the shortest and
longest string is three, so that not using pointers to strings saves
space even on 32bit systems.
Moreover, there is no need to use a sentinel here; it can be replaced
with FF_ARRAY_ELEMS.

The current setting for send-expect-100 option is either
enabled if applicable or forced enabled, no option to force
disable the header. This change is to expand the option setting
to provide more flexibility, which is useful for rstp case.

The "timeout" option name inherently clashes with the meaning of the
HTTP libavformat protocol option with the same name. Rename it after a
deprecation period to make it compatible with the HTTP one.
