[GSOC][PATCH 1/2] modified dir-iterator.c

[sushmaunnibhavi <sushmaunnibhavi425@gmail.com>]

---
Some places in git use raw API opendir/readdir/closedir to traverse a directory recursively, which usually involves function recursion. Now that we have struct dir_iterator,we have to convert these to use the dir-iterator to simplify the code.
