* 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
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`
`Gin` now have the `protobufBinding` function to check the request format, but didn't have a protobuf response function like `c.YAML()`.
In our company [ByteDance](http://bytedance.com/), the largest internet company using golang in China, we use `gin` to transfer __Protobuf__ instead of __Json__, we have to write some internal library to make some wrappers to achieve that, and the code is not elegant. So we really want such a feature.
