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.

As part of my timeofday rework, I've been looking at the NTP code and I
noticed that the PPC architecture is apparently misusing the NTP's
time_offset (it is a terrible name!) value as some form of timezone offset.
This could cause problems when time_offset changed by the NTP code. This
patch changes the PPC code so it uses a more clear local variable:
timezone_offset.

make defconfig give the following error on ppc (gcc-4):
arch/ppc/kernel/time.c:92: error: static declaration of ‘time_offset’
follows non-static declaration
include/linux/timex.h:236: error: previous declaration of ‘time_offset’
was here
The following patch solves it (time_offset is declared in timer.c).

The following problem was found by Giovambattista Pulcini
<gpulcini@swintel.it>, who also provided a partial patch, and this has been
verified by our time guru Gabriel Paubert <paubert@iram.es>.
The problem is that in do_settimeofday() we always set time_state to
TIME_ERROR and except on two platforms, never re-set it. This meant that
ntp_gettime() and ntp_adjtime() always returned TIME_ERROR, incorrectly.
Based on Gabriel's analysis, time_state is used for leap-second processing,
and ppc shouldn't be mucking with it.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
