Urban IshimweandGitHub 9519b9a9f5 Reduce allocation and unnecessary layers (#822) ...

The focus here was to **reduce allocation in TCP parser** but speed may have hopeful improved too!
pool no longer use map's key of **string** it uses **uint64**
**Benchmarks** was revamped to be more clear
if you want to compare these results copy the benchmark in tcp/bench_test.go@reduce-allocation to tcp/bench_test.go@master:

**before(master)**:
```
BenchmarkPacketParseAndSort-4         	 1000000	      1006 ns/op	      64 B/op	       2 allocs/op
BenchmarkMessageParserWithoutHint-4   	     625	   1772309 ns/op	      1000 packets/op	  419096 B/op	   10045 allocs/op
BenchmarkMessageParserWithHint-4      	      74	  14969926 ns/op	      1000 chunks/op	      1002 packets/op	  450992 B/op	   10126 allocs/op
```

**After(this branch)**:
```
BenchmarkPacketParseAndSort-4         	 1267662	       941 ns/op	      64 B/op	       2 allocs/op
BenchmarkMessageParserWithoutHint-4   	    2256	    523474 ns/op	      1000 packets/op	  243530 B/op	    1037 allocs/op
BenchmarkMessageParserWithHint-4      	      80	  13990955 ns/op	      1000 chunks/op	      1002 packets/op	  268609 B/op	    1099 allocs/op
