[PATCH v2 24/24] Rename functions to avoid breaking in-flight topics

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

The three functions init_revisions(), diff_setup() and rerere() are
prefixed temporarily with repo_ to avoid breaking other topics which
add new call sites for these functions. This is a temporary
measure. Once everything is merged, it will be reverted and the new
call sites fixed.
