Subject: [PATCH 01/15] contrib: add cocci script to replace index compat macros

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Sat, 16 Jun 2018 07:41:43 +0200

Index compat macros are going to be removed to expose the_index and
then reorganized to use the right index instead of simply the_index
because sometimes we want to use a different index.

This cocci script can help with the first step. It can be used later
on on even builtin/ when we start to reorganize code in there, but for
now this is the script that performs all the conversion outside
builtin/
