maintain our fReceiveNext member, or else the other endpoint never gets its
  data acknowledged. This fixes the ssl_closure test of the neon test suite,
  all tests finally go through.
* Use is_writable() in SendData() instead of checking all the states manually.
* Also bail out when the endpoint stops being writable when we were waiting
  for it to become writable.
