[PATCH] 'DONE' handler response

[Rob Hartill <ro...@imdb.com>]

I was told this was a feature and couldn't go into 1.2, so here it is
again. It adds a new handler response "DONE = -2" and handlers which
return it can inform Apache that the request has been handled and that
it can finish off the request quickly, as it does with errors, but without
groaning about an error (the request is logged).

About 50% of all requests to my servers go through this and I've been
using it for months. It seems to work :-)
