core: improve an existing data structures cloning in the SDP parser

It's been noticed that the cloning of SDP session(s) and
SDP stream(s) structures doesn't allocate the ICE candidate attributes,
nor it allocates (recently introduced) ICE media stream options.

In order to target this a couple of new functions have been introduced:
- clone_sdp_opt_attr()
- clone_sdp_ice_attr()

And additionally the following functions have been improved, in order to
properly clone/free ICE candidate attributes and (recently introduced)
ICE media stream options:
- clone_sdp_stream_cell()
- free_cloned_sdp_stream()
- free_sdp()
- print_sdp_stream()

Additionally for a proper new structure length calculation, the following
function is fixed:
- clone_sdp_session_cell()
