From f7d91ca2a3c562066f95db066381a8b956ded98f Mon Sep 17 00:00:00 2001
From: George Joseph <gjoseph@digium.com>
Date: Tue, 2 Jan 2018 06:36:46 -0700
Subject: [PATCH 5/5] timer: Clean up usage of timer heap
Added a new pj_timer_entry_reset function that resets a timer_entry
for re-use.
Changed direct settings of timer_entry fields to use
pj_timer_entry_init and pj_timer_entry_reset.
Fixed issues where timers were being rescheduled incorrectly.
