tcp: Make setsockopt(2) TCP_{NODELAY,NOPUSH,NOOPT,FASTKEEP} asynchronous
This makes all network system calls used by nginx asynchronous and greatly
improves nginx performance.
For 1 requests/connection (30K concurrent connections), this commit gives
12% improvement for 16KB web object (was 16.8Gbps, now 19.2Gbps, which
maxes out 2x10Ge). And it gives 19% improvement for 1KB web object (was
156Kreqs/s, now 186Kreqs/s).
