session tcp udp: consolidate transport snd apis
Type: improvement
Use only one api to retrieve transport send parameters. Additionally,
allow transports to request postponing and descheduling of events.
With this, tcp now requests descheduling of sessions when the
connections are stuck probing for zero snd_wnd
