es_main_dcl_module_n,	es_dcl_modules and es_expand_in_imp_module

uses an exported function from the current module

are lifted

added BVInt
removed symb_arity from SymbIdent

remove conversion table, except for macros

function expandMacrosInBody returns fi_dynamics instead of fun_info

(new: transform.[id]cl, check.icl, generics.icl)

out of range error reported by Peter.

better its use.

- unused dynamics in where/let clauses do not cause a rule doesn't match
  error in overloading.icl instead they are ignored
- default behaviour changed e.g.

f (i :: Int, j :: Int) = abort "Int"
f (r :: Real, s :: Real) = abort "Real"
f _ = abort "stop"

The compiler first matched on the tuple and then did the dynamic pattern
matches. But the last match did not call the last (default) alternative if it
did not match.
- some small changes

2. bugfix for fusion algorithm

changed Declaration type
fixed crash when macro appears only in dcl module
added make with caching in 'main'
use BoxedIdent in hashtable
