From 291d30c0662468866fd8ed6a64cfa04f5328cdbd Mon Sep 17 00:00:00 2001

Subject: [PATCH] Try harder to find a usable lttv in the tests scripts v2

Add many more attempts to auto-detect the path to the lttv executable or
the runlttv script in trace comparison tests.
Also support setting the LTTV env variable to directly set a path the
the lttv executable in addition to the RUNLTTV variable

Changelog:
   Correctly manage multiple traces

[ Edit: fix merge conflict ]
