Merge of r4892: keepalive memory usage optimization.

The ngx_http_keepalive_handler() function is now trying to not
keep c->buffer's memory for idle connections.

This behaviour is consistent with the ngx_http_set_keepalive()
function and it should decrease memory usage in some cases (especially
if epoll/rtsig is used).
