Scott Mitchell 06e7627b5f Read Only Http2Headers 
Motivation:
A read only implementation of Http2Headers can allow for a more efficient usage of memory and more performant combined construction and iteration during serialization.

Modifications:
- Add a new ReadOnlyHttp2Headers class

Result:
ReadOnlyHttp2Headers exists and can be used for performance reasons when appropriate.

Netty Project

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients.

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:

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.
