Reverted because it is a wrong solution.
Update http-parser and allow extra characters in TOKEN

Now http-parser is updated to cba704cb2d9f1df80994dd4a791a0fa6cce65720
We allow additional characters in TOKEN to access somewhat *broken*
servers. The all patches we made for spdylay are attached in this
directory.
