Check array function inputs.

[joaquinffernandez]

Bug*
We are getting compile time errors in defs like:

model array_params

constant Integer N = 10;

Real x[N];
discrete Real d;
parameter Real p[N];

function F
  input Real x[:];
  output Real y;
  external "C" y = sample(x) annotation(
                                Include="#include \"array_params.c\"");
end F;

initial algorithm
d := F(p);

equation
for i in 1:N loop
   der(x[i]) = 1;
end for;

algorithm

when time > 1 then
  d := F(x);
end when;
	annotation(

	experiment(
		MMO_Description="",
		MMO_Solver=QSS3,
		MMO_PartitionMethod=Metis,
		Jacobian=Dense,
		MMO_BDF_PDepth=1,
		MMO_BDF_Max_Step=0,
		StartTime=0.0,
		StopTime=1.0,
		Tolerance={1e-3},
		AbsTolerance={1e-3}
	));
end array_params;

with array_params.c:

int sample(double* arr) {
  return arr[0];
}
