net.server_epoll: Add option to defer accept() until data available
This is a Linux(?) socket option that delays the accept signal until
there is data available to read. E.g. with HTTP this might mean that a
whole request can be handled without going back trough another turn of
the main loop, and an initial client <stream> can be responded to.
This may have effects on latency and resource use, as the server does
not need to allocate resources until really needed.
