[3/4] widl: Declare fixed-size array args as pointers to arrays (can be applied alone)

[Dan Hipschman]

This patch makes it so widl can generate stubs for functions that take a
fixed-size array as an argument.  Currently, the generated code won't
compile because it tries to initialize an array to zero:

	int a[5];
	a = 0;

This makes widl declare the argument as a pointer to the array:

	int (*a)[5];

which is what midl does.  This patch shouldn't depend on the previous
patches, although the line numbers might be off, it should still apply.
I've sent the testcase for it (the next patch) seperately so this could
be applied even of the other patches aren't.
