[PATCH] NTP: ntp-helper functions

Browse source 
This patch cleans up a commonly repeated set of changes to the NTP state
variables by adding two helper inline functions:

ntp_clear(): Clears the ntp state variables

ntp_synced(): Returns 1 if the system is synced with a time server.

This was compile tested for alpha, arm, i386, x86-64, ppc64, s390, sparc,
sparc64.
