Spare some vclock_copy invocations because they could be expensive.

OK, you did a full-scale diff & merge. This could actually be
slower than the fast vclock_copy() which is available from the
previous patch. Let's discuss.
I think in a typical case we wouldn't have more than 1-2-3 active masters so
it could be even faster especially when we have more than 3-4 cluster members.
Also it could be worth if I make some bench for that.
