index: don't include nullid in len()
I suspect the reason the nullid is in the index in the last position
is that it lets index[i] for regular revision number, even when index
was just a regular Python list. An alternative solution would have
been to reserve revision number 0 for the null revision. I don't know
why that wasn't done. Now that we have classes backing the index, we
can easily make index[-1] get the nullid without having to put it last
in the list and including it in the len().
This patch just hides the nullid -- it will still be accessible at
index[len(index)].
I realize that this will be annoying when checking out across this
commit for debugging (including bisection).

==================================== Testing head checking code: Case A-7 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category A: simple case involving a branch being superceeded by another. TestCase 7: multi-changeset branch, split on multiple other, (head on its own branch), same number of head .. old-state: .. .. * 2 branch (1-changeset, and 2-changesets) .. .. new-state: .. .. * 1 new branch superceeding the head of the old-2-changesets-branch, .. * 1 new changesets on the old-1-changeset-branch superceeding the base of the other .. .. expected-result: .. .. * push allowed .. .. graph-summary: .. ..
