Add method name to execution message and call syscall

[lrettig]

Closes #111

[poszu]

What's the point of having it?

Suggested change

	#[allow(dead_code)]
	fn test3() {
	// no-op
	}

[lrettig]

the point is that this test should fail:

Lines 208 to 226 in 74b036a

	// this will execute a specific method
	let result = AthenaVm::new().execute(
	&mut host,
	AthenaRevision::AthenaFrontier,
	AthenaMessage::new(
	MessageKind::Call,
	0,
	1000000,
	Address::default(),
	Address::default(),
	None,
	Some("athexp_test3".as_bytes().to_vec()),
	Balance::default(),
	vec![],
	),
	elf,
	);
	// this should fail, as this method is not `callable`
	assert_eq!(result.status_code, StatusCode::Failure);

In other words, a method not marked #[callable] shouldn't be callable

[poszu]

It sounds more like a test of the procedural macro (which would check that methods not marked #[callable] are not exported in the macro). This test here would (should) fail even fn test3() was removed, right (it wouldn't find the method)?

[lrettig]

correct, but that would be testing something different :) if you think these tests should be restructured/moved, we can do that.
