Feature #1290: === Core: framework ===
remove global functions
|Status:||Resolved||Start date:||22 Nov 2016|
|Target version:||Sprint 33|
Now listed under Doxygen tab "Globals".
Some global functions are actually used in one file only => enclose them in an anonymous namespace.
Others are really meant to be global => consider enclosing them in an utility namespace, or refactor them into class member functions.
