convert atypical env_universal_common logging

Browse source 
This is a quick and dirty conversion of the atypical, and undocumented,
logging done by env_universal_common.cpp to the usual `debug()` pattern. I
didn't want to drop the messages because they could be useful when
debugging future issues. So I simply converted them to the lowest debug
level using the normal debug() function.

Fixes #2887
