stream: add *_get_data() function to obtain private data

Add new functions:

osmo_stream_server_link_get_data
osmo_stream_server_conn_get_data
osmo_stream_client_conn_get_data

To obtain private data from osmo_stream_* handlers.

This patch also introduces missing osmo_stream_server_conn_set_data.
