GZIPInputStream uses Inflater internally (so also native zlib). Inflater frees up memory only on explicit call to end() or during finalization (finalize() contains only call to end()), so GZIPInputStream should always be explicitly closed.
As native libraries are used a non-scalaish try-finally is used to avoid off-heap memory leak for GZIPInputStream and GZIPOutputStream in case of exceptions.
- created new subproject akka-protobuf (and added COPYING and LICENSE)
- renamed com.google.protobuf -> akka.protobuf everywhere
- also added such renaming step to the results of protoc compilation in
project/Protobuf.scala
- had to include transcriptions of Netty’s ProtobufEncoder/Decoder to
make multi-node-testkit compile again
