accept_connection(): Set NO_DELAY flag for the accepting socket

This significantly reduces the latency if the operating
system is not configured to set the flag by default.

For Windows the unnecessary delay has been reported
to be ~200ms while on ElectroBSD it's still 100ms.

Reported by Johan Sintorn in #894.
