DefaultHttp2ConnectionEncoder#writeHeaders shouldn't send GO_AWAY if stream is closed
Motivation: DefaultHttp2ConnectionEncoder#writeHeaders attempts to find a stream object, and if one doesn't exist it tries to create one. However in the event that the local endpoint has received a RST_STREAM frame before writing the response headers we attempt to create a stream. Since this stream ID is for the incorrect endpoint we then generate a GO_AWAY for what appears to be a protocol error, but can instead be failed locally. Modifications: - Just fail the local promise in the above situation instead of sending a GO_AWAY Result: Less severe consequences if the server asynchronously sends headers after a RST_STREAM has been received. Fixes https://github.com/netty/netty/issues/6906.

How to build
For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.
You require the following to build Netty:
- Latest stable Oracle JDK 7
- Latest stable Apache Maven
- If you are on Linux, you need additional development packages installed on your system, because you'll build the native transport.
Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.
Branches to look
Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>
. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.
