gram.y=>preproc.y II

Okay, here's my next version for you to look at/try. This versions needs NO
@ECPG commands in gram.y anymore. I found other ways to tell the script when to
do what. What still needs to be done is beautifying the script (I don't like
all those static declarations) and removing the remaining changes to gram.y.
There are only two left (variable handling on quite some places and
prepared_name twice).
