Add OpenBSD support, including pledge(2) support by implementing SYS_EnableSystemCallFilter(). This commit depends on the addition of AdjustFreq() privops and the addtion of invoking SYS_EnableSystemCallFilter() from PRV_StartHelper(). Only system call filter levels on/off' are supported. Setting level to 0 disables the filter and setting it to 1 enables it. Update the documentation to reflect that OpenBSD supports: - the SCHED_FIFO real-time scheduler (option -P) - locking chronyd into memory (option -m) - reload sample history of servers and ref clocks (option -r) - forking into two process when run as non-root user (option -u) - maxdrift/maxslewrate of 100000.
