Motivation:
At the moment when an unresolvable InetSocketAddress is passed into the epoll transport a NPE is thrown
Modifications:
Add check in place which will throw an UnknownHostException if an InetSocketAddress could not been resolved.
Result:
Proper handling of unresolvable InetSocketAddresses
This transport use JNI (C) to directly make use of epoll in Edge-Triggered mode for maximal performance on Linux. Beside this it also support using TCP_CORK and produce less GC then the NIO transport using JDK NIO.
It only builds on linux and skip the build if linux is not used. The transport produce a jar which contains all needed .so files for 32bit and 64 bit. The user only need to include the jar as dependency as usually
to make use of it and use the correct classes.
This includes also some cleanup of @trustin
