[PATCH 1/3][GSOC] diff: rename read_directory() to get_directory_list()

[Hiroyuki Sano <sh19910711@gmail.com>]

Including "dir.h" in "diff-no-index.c", it causes a compile error, because
the same name function read_directory() is declared globally in "dir.h".

This change is to avoid conflicts as above.
