timecounting: use C99-style initialization for all timecounter structs

Scott Cheloha
Hi,

If the timecounter struct changes again in the future it will be
easier to make the change if we are using C99-style initialization
everywhere.  In general I think C99-style initialization is easier to
read for larger structs.  The timecounter struct definitely qualifies
as "larger".  We probably should already be doing this but nobody has
bothered yet.

So I will bother.  This patch changes every timecounter struct to use
C99-style initialization.  Some are already using it but most are not.

Yes, I am aware that this is tedious to review.  I'm sorry.  I think
suffering this now will pay off in the future.

Speaking of the future: in a subsequent patch I would like to remove
several of the the zero and NULL members, as C99 guarantees that
omission of a member at initialization causes it to be implicitly
zeroed.  For instance, there is no reason to set .tc_user if the
timecounter has no corresponding driver in libc.  There are also no
drivers setting the .tc_poll_pps function pointer, so we can just let
it implicitly be NULL.  And if the timecounter needs no private cookie
we don't need to explicitly set .tc_priv to NULL.  Et cetera.

I suppose if people prefer it we _could_ do such changes in this
patch.  I'm leaning toward not doing that.  Switching to the C99 style
*and* dropping members will make review more difficult and increase
the likelihood of a mistake, i.e. I will accidentally break the build
on some platform and people will yell at me, which I want to avoid.

Thoughts?  Preferences?  ok?

Re: timecounting: use C99-style initialization for all timecounter structs

Nah, not bad at all. Could you check if you get identical object files
by chance? It would be a nice double check.

If others don't mind on some grounds, I'm fairly convinced of this being
a functional no-op and so: OK gnezdo@
