Split the project into the following modules: * common * buffer * codec * codec-http * transport * transport-* * handler * example * testsuite (integration tests that involve 2+ modules) * all (does nothing yet, but will make it generate netty.jar) This commit also fixes the compilation errors with transport-sctp on non-Linux systems. It will at least compile without complaints.
