Misleading error messages

[Martin Sjölund]

{{{package P

constant Real x = {1,1::2};
function fn

input Integer i;
output Real r;

algorithm

r := i;

end fn;

end P;

class A
Real a = P.fn(1);
end A;}}}

That model generates (using +g=MetaModelica) the following error:
{{{[a.mo:12:1-12:17:writable] Error: No matching function found for P.fn in component <NO COMPONENT>
[a.mo:12:1-12:17:writable] Error: Class P.fn not found in scope A.}}}

The problem is that we need to write specific error messages for each possible error as the compiler is currently written. There also needs to be more general error messages so that we at least start looking in the right direction.
(The error here is that x cannot instantiate; it's being partially instantiated when opening the scope P - there is no problem with P.fn)

This was fixed in the trunk with the addition of generic error messages for elabExp
