Handle HTTP/1.1 decode errors

[vietj]

Motivation: when the Netty HTTP/1.x decoder finds a protocol error (invalid chunk, initial line too long, etc...), it signals it with an error in the HttpObject. We handle it in a single case (http server invalid request) and we should handle it in all case on server request or in client response and make no further processing of the connection.

Changes: when an HttpObject is received we check there is no decode error. When there is a decode error we signal it to the HttpServerRequest or HttpClientResponse and then we close the connection.
