Server-sent-event fixes

This makes several changes to server-sent events to allow it to merge
to master.  The routing system has been removed in leiu of using
content-type eventstream detection.  Timers have been added to the
sse connections, and sse connections now rely on async_wait, rather
than a full read.

Tested: WIP
