Issue 4422/1: Remove parser/location global variable setup

Instead of relying on the global parser/location work horse (or
respective symbols in local scope), now fluids %parser/%location and
getter functions (*parser*)/(*location*) are employed for setting up the
general parsing and providing #{...#} with accurate information.

This patch removes the global setup and internal information flow: there
is still a variable "parser" being set in local parser modules.
