Subject async keepalive in http/2
Date Fri, 22 Jan 2016 14:12:53 GMT
With the timeout behaviour of SSL reads fixed, I am making another attempt at have http/2 connections
behave properly in async MPMs, e.g. event. One thing for that necessary as change in server
is the hook to send a last GOAWAY frame before the connection is closed. Not sending it seems
to confuse browsers, leading to unwanted failure of the subsequent request.

You opinion therefore is required. On inspection of the connection shutdown handling, it seems
that *all* MPM modules call, directly or indirectly, ap_start_lingering_close(). Keepalive
connections are still healthy at this point and pool cleanup happens later, so this seems
to be the place to install a new hook:

AP_DECLARE_HOOK(int,pre_close_connection,(conn_rec *c)) as RUN_ALL

Does this seem like the right place? Is the name any good? 

(forget the question about naming, should not have disturbed the beast...)
