sequencer: refactor check_todo_list() to work on a todo_list
This refactors check_todo_list() to work on a todo_list to avoid
redundant reads and writes to the disk. The function is renamed
todo_list_check(). The parsing of the two todo lists is left to the
caller.
As rebase -p still need to check the todo list from the disk, a new
function is introduced, check_todo_list_from_file(). It reads the file
from the disk, parses it, pass the todo_list to todo_list_check(), and
writes it back to the disk.
As get_missing_commit_check_level() and the enum
missing_commit_check_level are no longer needed inside of sequencer.c,
they are moved to rebase-interactive.c, and made static again.
