bisect: libify `check_merge_bases` and its dependents
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.
In `check_merge_bases()` there is an early success special case,
so we have introduced special error code
BISECT_INTERNAL_SUCCESS_MERGE_BASE (-11) which indicates early
success. This BISECT_INTERNAL_SUCCESS_MERGE_BASE is converted back
to BISECT_OK (0) in `check_good_are_ancestors_of_bad()`.
Update all callers to handle the error returns.
