Junio C Hamano c8c16f2865 diff-lib.c: constness strengthening ...

The internal implementation of diff-index codepath used to use non const
pointer to pass sha1 around, but it did not have to.  With this, we can
also lose the private no_sha1[] array, as we can use the public null_sha1[]
array that exists exactly for the same purpose.
