version 3.0.0

• Move almost all settings previously specified by command line options to config file.
• Minor cosmetic changes to command line option syntax for dory and other executables such as to_dory client program.
• Enable support for logging to a file. If file logging is enabled, SIGUSR1 causes dory to close and reopen its logfile, which facilitates logfile rotation. Log messages may now be written to any combination of (stdout/stderr, syslog, logfile).
• Improved handling of fatal errors, including stack traces and optional tracking of file descriptor usage for debugging.
• Use a dedicated thread for all signal handling. A minimal amount of work is now done in signal handlers, which wake up the signal handler thread to perform the bulk of the work in a normal thread context, eliminating concerns about the signal safety of various system-level APIs. All other threads, including the main thread, now run with all signals blocked, which eliminates concerns regarding system calls being interrupted by signals.
