Deprecate Keruald global functions
Open, LowPublic

Description

Plan is:

  • Move all content from rKGF to rKOT
  • rKGF is at this stage a wrapper for rKOT
  • Upgrade calling code to directly use rKOT
  • Deprecate and archive rKGF

Plan should also solve the dprint_r/dieprint_r issue: there are convenient methods to use as debug time. We should enable a global functions registration (in \ namespace, not in \Keruald) to ease debug with something like "DevUtils::registerGlobalFunctions();".
