MEDIUM: h2: properly consider all conditions for end of connection

During h2_wake(), there are various situations that can lead to the
connection being closed :
  - low-level connection error
  - read0 received
  - fatal error (ERROR2)
  - failed to emit a GOAWAY
  - empty stream list with max_id >= last_sid

In such cases, all streams are notified and we have to wait for all
streams to leave while doing nothing, or if the last stream is gone,
we can simply terminate the connection.

It's important to do this test there again because an error might arise
while trying to send a pending GOAWAY after the last stream for example,
thus there's possibly no way to get notified of a closing stream.
