v1.10.0: Improved diagnostics

This release unify and clear up logging so that module / function
informations are properly passed to logging function.
It does so by using default argument after variadic templates,
a feature introduced in v2.079.0 (2019-03-01),
and hence support for previous version has been dropped.
Additionally, exception stack trace will now properly print
as diagnostic, as advertised in the documentation.
