From: Pranit Bauva <pranit.bauva@xxxxxxxxx>
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 <negetive-value>`. Follow POSIX conventions to return
<negative-value> to indicate error.
Turn `exit()` to `return` calls in `bisect_checkout()`.
Handle this return in dependant methods - `check_merge_bases()`.
