Issue Description

Hi, may I ask why when new reset context, it set all properties to nil except for http.Request and http.ResponseWriter? What would be the problem if the implementation is the same as method NewContext?

[aldas]

echo.context is reused for http requests and between each request we need to reset it so there would not be data leaking from one request to other. We avoid using NewContext as much as possible to avoid allocating memory.

This happens here:

echo/echo.go

Lines 648 to 652 in 584cb85

	func (e *Echo) ServeHTTP(w http.ResponseWriter, r *http.Request) {
	// Acquire context
	c := e.pool.Get().(*context)
	c.Reset(r, w)
	var h HandlerFunc

and at the end of ServeHTTP that context is put back to pool to be used for another request.
