Added a new system call sys_timer.

Browse Source 
sys_timer accumulates timer ticks into seconds, minutes, hours and days.
It's left to the user to calculate from days into a date. It is not yet
known if the calculation is even roughly correct.

Reduced 2 kmem_reclaim/grant calls into one kmem_control call.
