Subject: [PATCH] Fix missing LIST_HEAD

Despite the presence of 'sys/queue.h' in some stdlib implementations
(i.e. uclibc) 'LIST_HEAD' macro can be missing.  This fix defines this
macro in the same manner as was done previously for 'TAILQ_'.

Fixes: #539
Closes: #639 (cherry-picked)
Backport: 2.1.9
(cherry picked from commit 95918754d2ba7e6bffe0fc74bebed60bd917c10c)
