PATCH: Introducing grokparm()

[Ziemowit Laski <zlaski at apple dot com>]

Next on my ObjC++ integration list is the grokparm() function, which
I need to call from c-parse.in.  After my c-parse.in changes get
integrated, I will then remove the groktypename_in_parm_context()
function, which will no longer be needed.

I will commit this as obvious.

        * c-decl.c (grokparm): New function.
        * c-tree.h (grokparm): New prototype.
