[GSoC][PATCH 0/3] clone: convert explicit dir traversal to dir-iterator

Add pedantic option to dir_iterator_begin at dir-iterator.c and convert explicit recursive directory traversal at copy_or_link_directory (builtin/clone.c) to the dir-iterator API.

This is my microproject for GSoC 2019. Idea taken from https://git.github.io/SoC-2019-Microprojects/#use-dir-iterator-to-avoid-explicit-recursive-directory-traversal

Build: https://travis-ci.org/MatheusBernardino/git/builds/497512561
