From 6fdb4834cdb5557d9bd7562f61984da8bd0d9c80 Mon Sep 17 00:00:00 2001
From: Laurent Bercot <ska-skaware@skarnet.org>
Date: Thu, 9 Sep 2021 19:58:12 +0000
Subject:  Prepare for 0.2.0.0, lots of changes.

- Make _r functions completely thread-safe.
- Save a lot of forking by having a persistent nsss_switch_query
- Introduce a timeout to make the server expire
- Start writing nsss-switch, not working yet.
