Many thanks to Michael Durrant for testing the below changes.

Compile and work on OSX/Darwin.
If we have no fork then we re-exec ourselves with --daemonised.
Improved the build system so we automatically detect if we need
librt or libresolv and if fork() works or not.
Move back to using librt for clock_gettime on Linux systems.
