Current Error Handling does not return false on logging errors

Inizia da RawSocketSender.java intorno alla riga 204 e segui il percorso di log() sia per i fallimenti della connessione sia per l’esaurimento dello spazio del buffer. Riproduci i due casi di errore descritti nell’issue, quindi verifica che log() segnali un fallimento invece di un successo quando una delle operazioni interne fallisce. Controlla l’issue #15 per il contesto esistente sulla gestione degli errori.

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.
