bisect: use new "struct argv_array" to prepare argv for "setup_revisions"
Because we will use other instances of this struct. The "rev_argv_push" function is changed into 2 functions "argv_array_push" and "argv_array_push_sha1" that take a "struct argv_array *" as first argument. And these functions are used to simplify "bisect_rev_setup". Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
