Add support for language-specific unparsing, to support many parameter data types for VHDL
Add support for expressions for array dimensions, sequence and string lengths, based on scalar parameters
Move parameter declarations to *-defs.vhd, with package body in "generics" in target dirs

eliminated "local" directory level, so core/local/util/* becomes core/util/*
