[PATCH v16 03/48] refs.c: constify the sha arguments for ref_transaction_create|delete|update

From: Ronnie Sahlberg <hidden>
Date: 2016-06-15 23:01:35
Subsystem: the rest · Maintainer: Linus Torvalds

ref_transaction_create|delete|update has no need to modify the sha1
arguments passed to it so it should use const unsigned char* instead
of unsigned char*.

Some functions, such as fast_forward_to(), already have its old/new
sha1 arguments as consts. This function will at some point need to
use ref_transaction_update() in which case this change is required.
