[parametric] new parametric process scheme
[parameter] paramproc ==> parameters
towards class translations
removed PropertyDefNode
better translation scheme

IF-THEN-ELSE conditional translation
translate methods return Result*
a big step by step towards reentrancy
[reentrant] testing ok
some minor cleanup
DTC ==> TDC, DRC ==> RDC
process_ref_translate becomes a function
