[Qemu-devel] [PATCH] some functions declared () rather than (void)

[Ian Jackson]

There are a few functions which are declared using this syntax
  return_value function()
when in fact they take no arguments and so should be
  return_value function(void)

The former is either a pre-ANSI declaration with unspecified argument
types (which is usually inappropriate), or a mistake by someone more
familiar with C++ than C.

I haven't changed all of the cases, just the ones where it seemed
clear that it should be changed.

Thanks,
Ian.
