timeval: Remove CACHE_TIME scheme.
		
This commit removes the CACHE_TIME scheme from timeval module.  This
is for eliminating the lock contention over the read/write lock of
the cached time.  To get the time, the thread now will directly do
the system call 'clock_gettime()'.

As a side effect, timer can only be warpped after timer is stopped
by 'appctl time/stop' command.
