rebase -i: rewrite init_basic_state() in C

This rewrites init_basic_state() from shell to C. The call to write_basic_state() in cmd_rebase__helper() is replaced by a call to the new function. The shell version is then stripped from git-rebase--interactive.sh. Signed-off-by: Alban Gruin <alban.gruin@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
