Merge in fix for threading (related to #140 and #187). This also includes the new feature that allow to submit a Runnable that gets executed later in the io thread.
* Overall code cleanup on FrameDecoder and ReplayingDecoder
* FrameDecoder discards readableBytes only when it has to
* Replaced createCumulationDynamicBuffer with newCumulationBuffer with
an additional hint
* ReplayingDecoder does not perform memory copy if possible
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.
