LogPrint's logger starts after the pidfile is initialized for some reason

[yangfl]

First, I'd like to thank you for fixing #1047.

However, I met the exact the same problem today. i2pd do exit with a non-zero return code, but still no other information is given. This makes debugging considerably a pain.

Please consider add some more error message to indicate what's going wrong.

It seems LogPrint() in UnixDaemon.cpp sometimes doesn't work. Try this (add syslog() call just near LogPrint() call)

                                pidFH = open(pidfile.c_str(), O_RDWR | O_CREAT, 0600);
                                if (pidFH < 0)
                                {
                                        syslog (LOG_USER|LOG_NOTICE, "%s %s %s %s %d\n", "Could not create PIDfile", pidfile.c_str(), strerror(errno), "pidFH:", pidFH);
                                        LogPrint(eLogError, "Daemon: could not create pid file ", pidfile, ": ", strerror(errno));
                                        return false;
                                }

yeah LogPrint's logger starts after the pidfile is initialized for some reason.
