Invalid code generation when function has `public` specifier only in its declaration

[Daniel-Cortez]

Issue description:

#include <a_samp>

public Func();
Func()
{
	printf("Func()");
}

main()
{
	printf("main()");
	CallLocalFunction("Func", "");
}

This code makes function main() call itself recursively, causing a stack/heap collision.
The reason is that Func() is defined without the public specifier and the function is not called directly, so the compiler doesn't generate any code for it, thinking it's unused. But because Func() has a public specifier in its declaration, the compiler still creates an entry for this function in the public functions table.
As a result, since there's no code for Func(), the entry points at main() instead, which causes recursion.

Minimal complete verifiable example (MCVE):

See above.

For now I'm not sure how to properly handle this bug.
Should we silently treat such functions as public, even if they don't have the public specifier in their definition, or rather issue error 025 (function heading differs from prototype)?
