6906853f8e Improve proxy/stub parameter passing for variadic OS interfaces. 
In the past a very low effort interface was used:

- All parmeters were treated as though they were type uinptr_t, and
- The maximum number of parmeters (6) was passed in all cases.

The first is potentially wrong and the second is very inefficient.  This commit improves this by:

- Making tools/mksyscall.c more intelligent, and
- Extending the syntax for variadic functions.

For example, in syscall.cvs, the open() API was represened like this:

    "open","fcntl.h","","int","const char*","int","..."

In reality, open may take only a single optional argument of type mode_t which is not the same size as uintptr_t.  And there is not reason to pass 6 parameters in that case.

And this has been extended to:

    "open","fcntl.h","","int","const char*","int","...","mode_t"

The existence of the "mode_t" tells tools/mksyscall that there is at most one optional parameter and, if present, it is of type mode_t.

6a3c2aded6 Fix wait loop and void cast (#24) 
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
