Current Error Handling does not return false on logging errors

Comienza con RawSocketSender.java alrededor de la línea 204 y sigue la ruta de log() tanto para los fallos de conexión como para el agotamiento del espacio del búfer. Reproduce los dos casos de fallo descritos en el issue y, después, verifica que log() informe de un fallo en lugar de un éxito cuando cualquiera de las operaciones internas falle. Consulta el issue #15 para ver el contexto existente del manejo de errores.

There are two types of errors I've run into:

1. Network Errors:
   Here I created an app to log to a remote Fluentd instance.
   private static final FluentLogger LOG = FluentLogger.getLogger("audit", "10.0.0.1", 22224);
   However, I forgot to start the remote Fluentd instance before running the app, so I got Network Errors
   java.net.ConnectException: Connection refused at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:345) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:589) at org.fluentd.logger.sender.RawSocketSender.connect(RawSocketSender.java:85) at org.fluentd.logger.sender.RawSocketSender.reconnect(RawSocketSender.java:98) at org.fluentd.logger.sender.RawSocketSender.flush(RawSocketSender.java:206) at org.fluentd.logger.sender.RawSocketSender.send(RawSocketSender.java:195) at org.fluentd.logger.sender.RawSocketSender.emit(RawSocketSender.java:157) at org.fluentd.logger.sender.RawSocketSender.emit(RawSocketSender.java:139) at org.fluentd.logger.sender.RawSocketSender.emit(RawSocketSender.java:134) at org.fluentd.logger.FluentLogger.log(FluentLogger.java:101) at org.fluentd.logger.FluentLogger.log(FluentLogger.java:86) at LoggerInfra.log(FluentdLoggerApp.java:27) at LoggerCaller.testLogger(FluentdLoggerApp.java:79) at FluentdLoggerApp.main(FluentdLoggerApp.java:112)

There error was printed to console (expected because of limited error handling #15), but the log() call returned true instead of false which hid the internal failure.
Result of logic in RawSocketSender.java#L204 which simple logs the error message to LOG.error().

2. A second error is that I ran out of buffer space. In this setup I had my app logging to a local Fluentd instance and buffering to file. The local instance then forwards the logs to a remote instance. However the remote instance was not running, so the local buffer space eventually got filled up. Again the log() call returned true and the stack trace was printed out to terminal.
