From b92fad2b7667df836f8ca4eb92d8c8be84bd0538 Mon Sep 17 00:00:00 2001

Subject: (MODULES-3961) emit more deprecation warnings

This now emits one deprecation warning for each function used (but not for each call-site). Prior to this, only a single deprecation warning would have been triggered, potentially misleading users.

Additionally this adds v4 deprecation stubs for the functions that were missed.
