[PATCH 7/8] Make O(n) algorithm the default implementation of --bisect

[Jon Seymour <jon.seymour@gmail.com>]

This patch makes the O(n) the default implementation of the git-rev-list
--bisect switch.

The original O(n^2) algorithm is still available as --bisect-orig.

It is left around to provide a quick and simple way to verify the
accuracy of the O(n) algorithm.

A subsequent patch is supplied to remove support for --bisect-orig
completely.

Linus: you may choose to defer application of this patch if you are
not confident that the O(n) algorithm is good.
