Generated services Iface/Client inner classes do not derive from base classes

When defining a service in Thrift, the generated code looks like

public class Service {
public interface Iface

{ ... }

public static class Client

{ ... }

}

This makes it quite hard to create generic classes which accept any kind of Client or Iface as a parameter. One such use case is the pooling of Client objects.

One way to circumvent this is to create a top level thrift service and have all other services extend it, but then there will be no coherency across the thrift community.

What about introducing a TService class:

public class TService {
public interface Iface {}
public static class Client {
public Client(TProtocol prot)

{ this(prot,prot); }

public Client(TProtocol iprot, TProtocol oprot) {}
}
}

and have generated services inherit from it:

public class Service {
public interface Iface extends TService.Iface {
}
public static class Client extends TService.Client {
}
}

As a bonus I'll contribute the pooling mechanism I've created for Bibale (based on GenericObjectPool).
