Move //pkg/gate.Gate to //pkg/sync.
- Use atomic add rather than CAS in every Gate method, which is slightly
faster in most cases.
- Implement Close wakeup using gopark/goready to avoid channel allocation.
New benchmarks:
name old time/op new time/op delta
GateEnterLeave-12 16.7ns ± 1% 10.3ns ± 1% -38.44% (p=0.000 n=9+8)
GateClose-12 50.2ns ± 8% 42.4ns ± 6% -15.44% (p=0.000 n=10+10)
GateEnterLeaveAsyncClose-12 972ns ± 2% 640ns ± 7% -34.15% (p=0.000 n=9+10)
