bisect: store good revisions in a "sha1_array"
This will make it easier to use good revisions for checking merge bases later. To simplify the code, a new "sha1_array_push" function is also introduced. And while at it we move the earlier part of the code to fill the argv that is passed to "setup_revisions", so that all this code is now completely after "read_bisect_refs".
