* Changed the _kern_exec() and _kern_load_image() syscalls. They expect

a flattened argument/environment buffer now. This simplifies the work
  for the kernel a bit, since it can just copy the buffer and check
  whether it looks OK instead of messing around with individual strings.
  The runtime loader also gets a flattened array.
* Set the maximum size of the arguments/environment buffer to 128 KB.
  When more arguments are passed, we fail with a proper error code
  (instead of just truncating the arguments as before).
* On exec*() the first argument was silently replaced by the given path
  name, which is not correct.
