Bugfixes to be added to 0.5.1

[Stephan Ewen]

I would like to add the following additions from the 0.6 branch to the 0.5.1 bugfix branch:

Small Bug Fixes:

Fix dependency exclusion for examples in yarn-uberjar

Fix maven enforcer plugin warnings in Eclipse

Fixes bugs where the TypeExtractor throws an NPE

Remove setUserCodeClassLoader() from PackagedProgram and use partial mock instead

Rework stratosphere-clients tests to not expect a binary blob jar file

Implement toString of CsvOutputFormat

Fix potential bug due to unnecessary cast from long to int in FSDataInputStream

Netty network stack

The following commits alltogether rework the network stack to use netty instead of custom NIO logic. It fixes an issue where in corner cases, some packets get lost.

Remove @Test from NettyConnectionManagerTest and run tests via main

Rename BufferAvailabilityRegistration constants

Check number of designated buffers before returning buffer

Add debug log messages to Netty stack

Replace custom Java NIO TCP/IP code with Netty 4 library

Offer buffer-oriented API for I/O

Hey,

I agree with the list.

There is already an issue to plan the 0.5.1 bugfix release: https://github.com/stratosphere/stratosphere/issues/886

I'm going to prepare (cherry-pick) the 0.5.1 release tomorrow, test it on a cluster and push it out as a bugfix release.
