[PATCH v2 1/3] dir: change the scope of function 'directory_exists_in_index()'

[Shourya Shukla <shouryashukla.oo@gmail.com>]

Change the scope of the function 'directory_exists_in_index()' as well
as declare it in 'dir.h'.

Since the return type of the function is the enumerator 'exist_status',
change its scope as well and declare it in 'dir.h'.
