From 4da25acb0ab964826f133025493a9b80d8bef509 Mon Sep 17 00:00:00 2001
From: Martin Mares <mj@ucw.cz>
Date: Sat, 5 Jun 2004 08:56:43 +0000
Subject: Cleaned up sk_reallocate() and friends. Also, removed the `if (s)'
 test, because I believe that as the whole socket interface doesn't accent
 NULL pointers, sk_reallocate() shouldn't be the only exception.
