globalvar: Add helper for deprecated variable names
When globalvars are renamed across releases it's not nice when variables
in the persistent environment loose their meaning. This adds a helper
function which adds an alias for the old names. When the persistent
variables still use the old names then their values are automatically
written to variables with the new names.
