serve: provide "receive" function for session-id capability

Rather than pulling the session-id string from the list of collected
capabilities, we can handle it as soon as we receive it. This gets us
closer to dropping the collected list entirely.

The behavior should be the same, with one exception. Previously if the
client sent us multiple session-id lines, we'd report only the first.
Now we'll pass each one along to trace2. This shouldn't matter in
practice, since clients shouldn't do that (and if they do, it's probably
sensible to log them all).

As this removes the last caller of the static has_capability(), we can
remove it, as well (and in fact we must to avoid -Wunused-function
complaining).
