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.
