* support bind http header param #1956
update #1956
```
package main
import (
"fmt"
"github.com/gin-gonic/gin"
)
type testHeader struct {
Rate int `header:"Rate"`
Domain string `header:"Domain"`
}
func main() {
r := gin.Default()
r.GET("/", func(c *gin.Context) {
h := testHeader{}
if err := c.ShouldBindHeader(&h); err != nil {
c.JSON(200, err)
}
fmt.Printf("%#v\n", h)
c.JSON(200, gin.H{"Rate": h.Rate, "Domain": h.Domain})
})
r.Run()
// client
// curl -H "rate:300" -H "domain:music" 127.0.0.1:8080/
// output
// {"Domain":"music","Rate":300}
}
```
* add unit test
* Modify the code to get the http header
When the http header is obtained in the standard library,
the key value will be modified by the CanonicalMIMEHeaderKey function,
and finally the value of the http header will be obtained from the map.
As follows.
```go
func (h MIMEHeader) Get(key string) string {
// ...
v := h[CanonicalMIMEHeaderKey(key)]
// ...
}
```

* Thanks to vkd for suggestions, modifying code
* Increase test coverage
env GOPATH=`pwd` go test github.com/gin-gonic/gin/binding -coverprofile=cover.prof
ok github.com/gin-gonic/gin/binding 0.015s coverage: 100.0% of statements
* Rollback check code
* add use case to README.md
* Fix context.Params race condition on Copy()
Using context.Param(key) on a context.Copy inside a goroutine
may lead to incorrect value on a high load, where another request
overwrite a Param
* Using waitgroup to wait asynchronous test case
* Add context.HandlerNames()
This change adds a HandlerNames method that will return all registered handles in the context, in descending order
This is useful for debugging and troubleshooting purposes, especially in large apps
* Tests
Add tests for HandlerNames
* Fix HandlerNames test
* Simplify test
* fix Context.Next() - recheck len of handlers every iteration
* add tests when Context.reset() can be called inside of handler
TestEngineHandleContext
TestContextResetInHandler
TestRouterStaticFSFileNotFound
* Context.Next() - format to while style
*gin.Context implements standard context.Context methods, but always
returns data as context is still valid. Since Go 1.7, http.Request now
contains a context.Context object, which can be controlled by the
http.Server to indicates that the context is now closed, and persue of
request should be canceled.
This implements the propagation of http.Request context methods inside
gin.Context to have HTTP context cancelation information at gin.Context
level.

When `gin.Context.FormFile("...")` is called the `engine.MaxMultipartMemory` is never used. This PR makes sure that the `MaxMultipartMemory` is passed and removes 2 calls to `http.Request.ParseForm` since they are called from `http.Request.ParseMultipartForm`
