[PATCH v3 1/2][GSoC] diff-no-index: rename read_directory()

[Brian Bourn <ba.bourn@gmail.com>]

It would be desirable to replace manual checking of "." or ".."
in diff-no-index.c with is_dot_or_dotdot(), which is defined
in dir.h, however, dir.h declares a read_directory() which conflicts
with a (different) static read_directory() defined
in diff-no-index.c. As a preparatory step, rename the local
read_directory() to avoid the collision.
