hwclock: don't drop valid samples in HCL_ProcessReadings()

Browse Source 
Modify the HCL_ProcessReadings() function to try to always provide
a valid sample. Instead of dropping a sample outside of the expected
delay, provide its assumed quality level as a small integer (relative to
already accumulated samples), and let the caller decide what quality is
acceptable.
