libc: add clock_settime() system call. This also adds the sys_settime() kernel call which allows for the adjusting of the clock named realtime in the kernel. The existing sys_stime() function is still needed for a separate job (setting the boottime). The boottime is set in the readclock driver. The sys_settime() interface is meant to be flexible and will support both clock_settime() and adjtime() when adjtime() is implemented later. settimeofday() was adjusted to use the clock_settime() interface. One side note discovered during testing: uptime(1) (part of the last(1)), uses wtmp to determine boottime (not Minix's times(2)). This leads `uptime` to report odd results when you set the time to a time prior to boottime. This isn't a new bug introduced by my changes. It's been there for a while. 2013-03-30 17:59:21 +01:00			`#include "syslib.h"`
