This touches only MI code, and adds new time keeping code. The

code is all conditionalized on __HAVE_TIMECOUNTER, and not
enabled on any platforms.

adjtime(2) support exists, courtesy of nordin@, sysctl(2) support
and a concept of quality for each time source attached exists.

High quality time sources exists for PIIX4 ACPI timer as well as
some AMD power management chips.  This will have to be redone
once we actually add ACPI support (at that time we need to use
the ACPI interfaces to get at these clocks).
