The `struct rebase_options::default_backend` field is a non-constant string, but is being assigned a constant via `REBASE_OPTIONS_INIT`. Refactor the code to initialize and release options via two functions `rebase_options_init()` and `rebase_options_release()`. Like this, we can easily adapt the former funnction to use `xstrdup()` on the default value without hiding it away in a macro.
