History
Jérôme Duval 7065a89fc6 POSIX: ioctl(fd, op, arg) equals ioctl(fd, op, arg, 0) 
The ioctl call cannot know the expected number of arguments
because it depends on the specific ioctl being used, and the
same value could be used to do different things by different
devices. Without knowing that, it is not safe to use va_arg
(at best a random value will be read from the stack, at worst,
it will just crash).

This changes the implementation of ioctl in two ways:
- For C++ code: a 4 argument function with default values
  for arguments 3 and 4.
- For C code: wrap arguments 3 and 4 in a struct with the
  help of a macro, providing something that behaves like the
  C++ version.

So, with this new code:
- Calling ioctl with only 3 arguments sets the 4th one to 0
- Calling ioctl with only 2 arguments sets the 3rd and 4th to 0
- Calling with 1 or 5+ arguments is a compile time error

The existing ioctl symbol is preserved for ABI compatibility.
