I removed the MULTI_KBOARD define, it was set like that by mistake when
I did the initial multi-tty port to Carbon, and nobody has touched it
much since. Given that now the Carbon port warns that it is non
functional, if anybody wants to get this working, it should be done the
right way.

It's not at the top level, it's in x-setup-function-keys. 
It's confusing because the function is not indented. When I did the
initial multi-tty port I didn't want to make unnecessary changes that
would make merging harder. There's more stuff that needs to be properly
indented in the file, but that would make the unicode-2 merge harder.

I changed it to be similar to what w32-win.el does.

None of these is tested, I don't have access to a mac machine.
