Patrick Steinhardt 45843d8f4e commit-reach: use size_t to track indices in remove_redundant() ...

The function `remove_redundant()` gets as input an array of commits as
well as the size of that array and then drops redundant commits from
that array. It then returns either `-1` in case an error occurred, or
the new number of items in the array.

The function receives and returns these sizes with a signed integer,
which causes several warnings with -Wsign-compare. Fix this issue by
consistently using `size_t` to track array indices and splitting up
the returned value into a returned error code and a separate out pointer
for the new computed size.

Note that `get_merge_bases_many()` and related functions still track
array sizes as a signed integer. This will be fixed in a subsequent
commit.
