Version 1.1pre12 released.

* Added a "--syslog" option to force logging to syslog even if running in the
  foreground.
* Fixes and improvements to the DecrementTTL function.
* Improved PMTU discovery and UDP keepalive probes.
* More efficient relaying of UDP packets through intermediate nodes.
* Improved compatibility with newer TAP-Win32 drivers.

* Allow tinc to be compiled without LibreSSL or OpenSSL (this drops
  compatibility with nodes running 1.0.x).

* Tinc "start" now checks whether the daemon really started succesfully, and
  displays error messages otherwise.
* Added systemd service files.
* Use the recvmmsg() function if available.
* Support ToS/Diffserv on IPv6 connections.
* Updated support for BSD tun/tap devices.
* Added support for OS X utun interfaces.
