[PATCH v8 0/6] Finish converting git bisect to C part 2 subset 1

These patches correspond to a second part of patch series 
of Outreachy project "Finish converting `git bisect` from shell to C" 
started by Pranit Bauva and Tanushree Tumane
(https://public-inbox.org/git/pull.117.git.gitgitgadget@gmail.com) and
continued by me.

This patch series version is composed by the first six patches of the
previous version due to a bug discovered during the test stage, that 
affects the rest of the patches and that needs to be fixed before 
sending them.

These patch series emails were generated from:
https://gitlab.com/mirucam/git/commits/git-bisect-work-part2-v8-subset1.

I would like to thank Johannes Schindelin for reviewing this patch series
and to Christian Couder for his advice and help.
