mf: Handle MESourceSeeked and MEStreamSeeked state change events.

If a session is paused then started again, or if a start position is
provided we wait forever for the source to send a MESourceStarted event,
when it sends a MESourceSeeked instead.

This causes a deadlock in Bright Memory: Infinite as the game then waits
for the Start command to complete, while the session is stuck in the
SESSION_STATE_STARTING_SOURCES state.
