[PATCH] fix declarations

[Mohammad-Reza Nabipoor]

* jitter/jitter-missing.h (flockfile): Add param.
(funlockfile): Likewise.

* templates/vm.h (enum vmprefix_exit_status): Put declaration
before the first use.

Hello, Luca.

I tried to use a jittery vm in a C++ program, the compiler complained
about these inconsistencies in header files.
This patch fix those problems.

But there's still a problem: The `restrict` keyword, which is a C99
keyword, not a C++ keyword.

So, I used the `vmprefix-vm.h` in my code like this:

```c++
extern "C" {
#define restrict
#include "vmprefix-vm.h"
}
```

But I think, it'd be nice if jitter handle this case.
For more info: https://gcc.gnu.org/onlinedocs/gcc/Restricted-Pointers.html


Regards,
Mohammad-Reza
