This rewrites (the misnamed) setup_reflog_action() from shell to C. The new version is called prepare_branch_to_be_rebased(). A new command is added to rebase--helper.c, “checkout-base”, as well as a new flag, “verbose”, to avoid silencing the output of the checkout operation called by checkout_base_commit(). The function `run_git_checkout()` will also be used in the next commit, therefore its code is not part of `checkout_base_commit()`. The shell version is then stripped in favour of a call to the helper. As $GIT_REFLOG_ACTION is no longer set at the first call of checkout_onto(), a call to comment_for_reflog() is added at the beginning of this function.
