[sr-dev] sdpops: new function sdp_get_ip_c

Hello Konstantin,

attached patch provides a function that gets ports and stores them in an 
AVP variable.

However, there are other approaches to create these functions:

- A function to return each parameter (sdp_get_ip_c, sdp_get_port, etc)

- An only function sdp_get_address which return two AVP variables, IP 
and port for each stream.

- A generic function sdp_get_stream_info which receives an enum 
indicating what variable do you like and return it.

- Two functions: sdp_get_stream_count, sdp_get_stream_info(stream_num, 
enum_variable, pseudo_variable)
First would get total number of streams (asuming one session in 
offer/answer way), and second function would return that variable value 
for a stream.

Daniel, as sdpops maintainer which approach would you rather?

Kind regards,
