Hello!

Looking through context package and found a little bit complicated switch block. And tried to make it easier.

Thanks!

return json if jsonp has not callback

add a json render that rendering json as ASCII string

- update assert param(expect, actual) position

the pull request update `return error(err)` to `return err`, and remove `kindOfData`.

ref #1075 
annotation from go context source.

* add go version prerequisite and debug warning

* merge duplicate content

* remove duplicate content

updated `vendor.json` is ok.
but set `ignore test` in `vendor.json`, `x/net/context` package only use in `context_test.go`, I don't know why vendor still need it.
please @appleboy review the pull request, thanks a lot.

sorry...fixed #1403 

use grpc helloworld example.

gin already support http2, while previously not support server push.
Add Pusher() function to extend the ResponseWriter interface.

```golang
// get http.Pusher
 if pusher := c.Writer.Pusher(); pusher != nil {
     // use pusher.Push() to do server push
}
```

And I test them benchmark:

code:

```go
# stringsbench.go
package stringsbench

import "strings"

func index(part string) string {
	if index := strings.IndexByte(part, ';'); index >= 0 {
		if part := strings.TrimSpace(strings.Split(part, ";")[0]); part != "" {
			return part[0:index]
		}
	}
	return ""
}

func split(part string) string {
	return strings.Split(part, ";")[0]
}
```

```go
# stringsbench_test.go
package stringsbench

import (
	"testing"
)

func BenchmarkIndex(b *testing.B) {
	b.RunParallel(func(pb *testing.PB) {
		for pb.Next() {
			index("text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8")
		}
	})
}

func BenchmarkSplit(b *testing.B) {
	b.RunParallel(func(pb *testing.PB) {
		for pb.Next() {
			split("text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8")
		}
	})
}
```

And the result:

```shell
➜  strings go test --bench=.
goos: darwin
goarch: amd64
BenchmarkIndex-8   	30000000	        46.1 ns/op

Reference this issue #1323 

1. There isn't any eg about `HandleContext`  
2. The `c.Request.Path`  of `HandleContext` Comment  is not right   

Based on the above two points, I pull this request.  
If you think it's unnecessary, I will close this.  
Thx.
