Subject: slirp: replace qemu_notify_event() with a callback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Introduce a SlirpCb callback to kick the main io-thread.

Add an intermediary sodrop() function that will call SlirpCb.notify
callback when sbdrop() returns true.
