Since we want to get rid of git-bisect.sh, it would be necessary to convert those exit() calls to return statements so that errors can be reported. Emulate try catch in C by converting `exit(<positive-value>)` to `return <negative-value>`. Follow POSIX conventions to return <negative-value> to indicate error. All the functions calling `bisect_next_all()` are already able to handle return values from it.
